STORMWATER PROGRAM BACKGROUND Introduction: The Town of Oro Valley (Town) manages stormwater quality in accordance with the Arizona Pollutant Discharge Elimination System (AZPDES) Permit AZG2021-002 that authorizes the discharge of stormwater from the municipal separate storm sewer system (MS4) to receiving waters. The MS4 generally consists of roads, storm drains, and infrastructure carrying runoff into drainage ways or ephemeral stream channels. This Stormwater Management Program (SWMP) describes the control measures the Town of Oro Valley uses to manage the quality of discharges from the MS4. These Minimum Control Measures (MCMs) are: 1. Public Education and Outreach 2. Public Participation and Involvement 3. Illicit Discharge Detection and Elimination 4. Construction Site Runoff Control 5. Post-Construction Runoff Control 6. Pollution Prevention/Good Housekeeping for Municipal Operations Regulatory Framework: Stormwater regulations originated with the federal Clean Water Act, which includes the delegation of the program to qualified states. In Arizona, the state issues MS4 permits. Local jurisdictions, including the Town of Oro Valley, have also written ordinances and policies impacting stormwater management. Clean Water Act Phase I of the U.S. Environmental Protection Agency’s (EPA) Municipal Stormwater Program was promulgated in 1990 under the authority of the 1972 Clean Water Act (CWA). Phase I relied on the National Pollutant Discharge Elimination System (NPDES) permit coverage to address stormwater runoff from medium and large municipal separate storm sewer systems (MS4’s) serving municipalities with populations greater than 100,000, construction activities disturbing 5 acres of land or more, and 10 categories of industrial activity. The Stormwater Phase II Final Rule, which the Town of Oro Valley is operating under, is published in Code of Federal Regulations 40 (CFR40) and was promulgated December 8, 1999. This was the next step in the EPA’s effort to preserve, protect and improve the nation’s water resources through regulation of stormwater runoff from small MS4 operators. AZPDES Program The Stormwater Phase II regulations in Arizona are administered by the Arizona Department of Environmental Quality (ADEQ). The current Arizona State General Permit AZG2021-002 was adopted September 30, 2021. Local Regulations The Town of Oro Valley adopted its first Storm Water Quality and Discharge Control Ordinance in 2001 in compliance with Federal and State regulations. The primary objectives of the Town regulations were to prevent, control, and reduce stormwater pollution from construction sites, as well as to detect and eliminate illicit discharges. In July 2001 the Oro Valley Town Council created the Stormwater Utility (SWU) along with a 4 October 31, 2021 Stormwater Utility Commission (SWUC). In March 2003 the Town submitted its first Stormwater Management Program (SWMP) to the ADEQ. This document updates the SWMP for the current and continuing program. The mission statement of the Stormwater Utility is to promote and protect life and safety, water quality, and the Town’s working and natural environments before, during, and after the occurrence of storm events in accordance with all applicable codes, standards and policies. Geographic Setting: Oro Valley is located in northeastern Pima County, approximately three miles north of the City of Tucson. The Town is located between the Santa Catalina and Tortolita mountains and varies in elevation from 2,380 feet to 3560 feet. The Town covers an area of 36 square miles and is home to more than 47,070 residents. It was incorporated in 1974 and employs a council-manager form of municipal government with a mayor and seven- member Town Council. Receiving Waters and Outfalls: The Town of Oro Valley has two Receiving Waters. These are Big Wash and the Canada Del Oro Wash. Big Wash has nine (9) private outfall discharge points, and the Canada Del Oro Wash (CDO) has 14 total outfalls, with nine (9) of those being municipal outfall discharge points. Surface water quality standards (SWQS) have been established and are enforced by the Arizona Department of Environmental Quality (ADEQ) under Arizona Revised Statute 49-222 of the Arizona Administrative Code. Currently the Town of Oro Valley has no discharges which contribute to an exceedance of applicable state of Arizona mandated SWQS. Similarly, the Town of Oro Valley does not discharge into any Waters of the United States with restrictions to Total Maximum Daily Loads (TMDL) and Waste Load Allocations (WLA). Neither Big Wash nor the CDO have been designated as Impaired, Non- Attaining, or an Outstanding Arizona Water. Similarly, neither of these receiving waters have TDML restrictions. Town of Oro Valley Stormwater Infrastructure Mapping: The Town of Oro Valley maintains detailed maps of all stormwater infrastructure within the town limits, a representation of which can be seen in Attachment C of this report. The current inventory of the Town’s stormwater infrastructure includes: Town of Oro Valley Stormwater Infrastructure 2021 Miles of Roads 203 Constructed Channels 1099 Culverts (Pipe and Box) 593 Storm Drain Pipes 1113 Catchbasin Inlets 1923 Stormwater Detention Basins 232 First-Flush Filtration Devices 175 Miles of Mapped Washes (Natural) 229 The Town’s stormwater system map was created using ArcGIS asset-management software, in combination with aerial photographs and construction plans for the street and drainage systems and is updated on a continuous basis as new assets are either created through the development/re-development process, or discovered through 5 October 31, 2021 the Town’s asset inspection process. This software is used for visualizing, managing, creating, and analyzing geographic data unique to this community. II. STORMWATER CONTROL MEASURES There are six minimum control measures (MCM’s) specified in section 6.0 of the Arizona State General Permit. From these, the Town has created its own unique set of best management practices (BMP’s) to address the required MCM’s to the maximum extent practicable. Furthermore, for each BMP, the Town has identified implementation dates and frequency, measurable goals, and responsible department, as outlined in Attachment D. MCM-1 Public Education and Outreach In order to promote public awareness and interest in stormwater quality issues, the Town utilizes public outreach and education activities aimed at targeted public sectors. The requirements for this section are outlined in the Arizona State General Permit section 6.1. The Arizona State General Permit requires implementation of a public outreach and education program consisting of activities and materials designed to educate the public on stormwater quality issues. The Town will be reaching out to residents, businesses, churches, schools, Town employees, and the general public during the implementation of this program. Audiences will be chosen from a diverse cross section of the Town, focusing on constituents who possess the largest potential for reducing stormwater pollution. The pollutants targeted by the public outreach and education program are: • sediment from construction sites; • toxic chemicals from motor vehicles; • herbicides, pesticides, nutrients from lawns and gardens; • industrial and commercial waste; and • bacterial and viral problems associated with pet waste. The following BMP’s have been selected as the best approach to meeting the Town’s public outreach and education minimum control measure. BMP 1.1 Create and Update Informational Brochures The stormwater management objective of this program is to foster and promote an informed and proactive public. Informational brochures or fact sheets will be updated and made ready for distribution. Topics may include proper pet waste disposal, safe swimming pool discharge, safe household and industrial chemical disposal, and resident participation and volunteer opportunities. Measurable goals for this BMP shall be the number of brochures created, and the targeted audiences addressed each year. This is an ongoing activity. BMP 1.2 Distribution of Informational Brochures to the General Public Informational brochures will be distributed to the general public by mail to the 19,400 water utility customers annually. The SWU will also be present at various Town events distributing information on water quality and best practices pertaining to stormwater quality. The measurable goal for this BMP shall be the number of 6 October 31, 2021 impressions/interactions made through each public outreach event or mailing. An additional goal, once measurable, may be a quantifiable reduction in the volume of pollution over time. This is an ongoing activity. BMP 1.3 Distribution of Brochures to Businesses That Potentially Affect Stormwater Quality Informational brochures will be developed for targeted businesses. One business sector will be targeted each year. Targeted businesses will include those involved in home construction and repair, commercial construction, auto service and repair, garden centers, food-service, and commercial and residential cleaning services. SWU staff will target one business type each year for bulk outreach mailing. The measurable goal for this BMP shall be the number of brochures mailed each year to each targeted business sector. This activity is done annually. BMP 1.4 Stormwater content in the Oro Valley Vista Newsletter The SWU staff will prepare brief public-information articles on best practices and stormwater quality for publication in the Town of Oro Valley Vista Newsletter. The Oro Valley Vista Newsletter is published monthly via the town website, www.orovalleyaz.gov, as well as distributed to every water utility customer via their water bill. Stormwater information will be submitted for publication and disseminated one time each year. The measurable goal for this BMP shall be the number of website hits, and the number of newsletters mailed via the water utility billing process. This activity is done annually. BMP 1.5 Outreach Events at Town of Oro Valley Schools Educational materials including power point presentations, will be updated and expanded. Topics will include promotion of a litter free environment and environmental awareness and stewardship. Targeted age groups will be elementary school aged children. SWU staff will review and update existing presentation materials and purchase appropriate take home materials to be given away as reminders of these events. In addition, SWU staff will be available should a school or another organization request a speaker. Staff goal is to provide an average of one outreach school presentation each year. The measurable goal for this BMP shall be the number of impressions/interactions made through each public outreach school event. This activity is ongoing and done annually. BMP 1.6 Display of Outreach Materials on Town Owned Sun Shuttle Buses Outreach displays will be placed on Town owned Sun Shuttle buses. The informational content will be developed and displayed with cooperation from the Pima County Association of Governments (PAG) Stormwater Management Working group. Content will be developed one time each year. The goal is to target one half of the Town-owned bus fleet (or 7 buses) each year. The measurable goal for this BMP shall be the number of impressions made through this program. This will be measured based on ridership statistics provided by the Town of Oro Valley transit division. This activity is ongoing and continuous. BMP 1.7 Stormwater Content on the Town of Oro Valley Website The SWU staff will review and update stormwater-related webpage content twice each year. Home owners associations (HOA’s) will also be encouraged to post fact sheets and other stormwater-related content on their webpages. The measurable goal for this BMP shall be the number of website hits annually on the Stormwater portion of the Town of Oro Valley website. 7 October 31, 2021 BMP 1.8 Effective Response to Public Inquiries The Town of Oro Valley consistently and effectively responds to public inquiries regarding stormwater quality, illicit disposal of wastes, and public requests for information. The Town of Oro Valley has identified two principal contacts for best response and follow up procedures on these public inquiries: the Stormwater Utility Manager and the Constituent Services Coordinator. The Town fields and processes these inquires through multiple avenues. Citizens have the ability to report problems and ask questions via dedicated e-mail, telephone, or an online portal. The measurable goal for this BMP shall be the number of water quality related public inquiries responded to and resolved each year by the Stormwater Utility. This activity is ongoing and continuous. MCM-2 Public Participation and Involvement Oro Valley constituents are actively engaged in many aspects of the Town’s governance, including involvement with commissions, neighborhood associations, volunteering for various departments within the Town, and electronic correspondence. The SWU utilizes neighborhood meetings with SWU staff, maintains effective communication through use of the Town’s website, and outreach by SWU staff. The Town’s SWMP works to tap into these existing public participation and public involvement activities in order to solicit input on specific activities and decisions that affect the residents and businesses of Oro Valley. The SWU has elected to adopt the following five high-impact BMP’s in order to meet and exceed the requirements of MCM-2. BMP 2.1 Public Participation Through the Stormwater Utility Commission (SWUC) The Town created the 5-member volunteer SWUC in 2001 to provide guidance through monthly meetings focusing on, the development and implementation of the SWMP, development of fair and effective policies, definition of service levels, assessment of revenue requirements, and monthly and annual review of budgetary effectiveness and efficiency. The measurable goal for this BMP shall be the number of meetings conducted each reporting year. BMP 2.2 Public involvement Through Notification of Monthly SWUC Meetings Official notices of public meetings, including SWUC meetings, are made in accordance with established Town procedures, including publication on the Town webpage and in a local newspaper, making notices available at the Town Clerk’s Office, and posting bulletins in prominent locations around the meeting area. The measurable goal for this BMP shall be an ongoing policy of posting these meeting notices within the listed locations throughout Town. BMP 2.3 Public Interaction with SWU Staff The Town of Oro Valley SWU effectively responds to public inquiries regarding stormwater quality, illicit disposal of wastes, and requests for information. Complaints, comments and concerns are tracked using the Town’s web-based Cartegraph Operations Asset Management System (OMS). Constituents can make reports via phone (520) 229-4850, email pw@orovalleyaz.gov, or online portal www.orovalleyaz.gov; SWU staff respond to requests by creating tasks to inspect issues and address concerns. The measurable goal for this BMP shall be, maintaining these avenues by which the public may express concerns about water quality issues, and logging of, and expeditious investigation of all constituent concerns. 8 October 31, 2021 BMP 2.4 Solicitation of Public Comments Regarding Key Components of Utility Operations The Town of Oro Valley will provide residents and businesses the opportunity to view and comment on stormwater-related Town ordinances, the SWMP, and NOI’s. These documents will be made available on the Town’s website and upon request with the Town Clerk’s office at Town Hall. Constituents will be notified of any change to these documents via town-wide press release. The measurable goal for this BMP shall be an ongoing policy of posting these stormwater related documents to the Town website as well as making these documents available through the Town Clerk’s office. BMP 2.5 Encouragement of Public Participation via Volunteer Groups Sponsored by the Town of Oro Valley The Town solicits public involvement through the “Adopt-A-“ programs, some of which have been in place since January, 2001. These programs serve multiple purposes, and are modeled after the highly successful programs at the State of Arizona and Pima County. The “Adopt-A-“ programs facilitate removal of trash and other pollutants from parks, trails, roadways and washes, affecting immediate and direct positive impacts to stormwater quality. These programs also serve as extra sets of eyes focused on potential illicit discharges, connections, and dumping into the MS4. The Town has observed these programs to serve as a crucial educational tool for the public on the importance of water quality as it relates to pollution and stormwater. Measurable goals for this BMP shall be the number of cleanups, and the number of people involved each reporting year. MCM-3 Illicit Discharge Detection and Elimination Oro Valley’s SWU is responsible for implementing an Illicit Discharge Detection and Elimination System (IDDE) designed to eliminate illicit discharges, illicit connections, and improper disposal (dumping) into the MS4.This section outlines the Town’s approach to prevent these discharges into the MS4 via legal, technical, and educational means within the scope of this SWMP. According to Section 6.3 of the State of Arizona AZG2021-002 phase II MS4 General Permit, the SWMP allows the following non-stormwater discharges. However, The following categories of non-stormwater discharges or flows shall be addressed when such discharges are identified by the permittee as sources of pollutants to a protected surface water: • Water line flushing • Landscape irrigation, including flood irrigation • Diverted stream flows • Rising ground waters • Uncontaminated groundwater infiltration (as defined in 40 CFR 35.2005(b)(20)) to separate storm sewers: • Uncontaminated pumped groundwater • Discharges from potable water sources • Foundation drains • Air conditioning condensation • Irrigation water • Springs • Water from crawl space pumps • Footing drains • Lawn watering 9 October 31, 2021 • Individual residential car washing • Flows from riparian habitats and wetlands • Dechlorinated swimming pool discharges • Street wash water • Discharges or flows from emergency firefighting activities • Discharges authorized by another NPDES or AZPDES permit All other non-stormwater discharges to the MS4 are prohibited. The SWU actively seeks to detect, eliminate, respond to and prevent illicit discharges to the MS4 through the following BMP’s: BMP 3.1 Implementation of an IDDE Program Town Code 15-24 provides the regulatory framework for managing, implementing, and enforcing stormwater regulations, including IDDE. SWU staff annually review the Stormwater Ordinance for compliance with current state regulations, as well as its effectiveness in providing uniform compliance. Measurable goals for this BMP shall be the amount of storm system inspected annually (20%), the number of proactive inspections of private infrastructure performed, number of illicit discharges detected and eliminated, number of facilities /construction sites observed and reported to ADEQ that discharge without an AZPDES/NPDES permit, and the number of enforcement actions taken (including: notices of violation, or other educational and enforcement actions). BMP 3.2 Identification and Mapping of the MS4 SWU staff maintain and update the Town of Oro Valley MS4 asset map (begun in 2007) as new Stormwater assets are either discovered through the MS4 asset-inspection process, or through new installation as part of recent development/re-development. Measurable goals for this BMP shall be the mapping of 100% of new MS4 assets created through the development/re-development process each reporting year, as well as updating the MS4 map in an ongoing and continuous basis with newly discovered assets through the Town’s MS4 asset-inspection process. BMP 3.3 Identification and Mapping of the Town’s Municipal Outfall Inventory Municipal outfalls as well as other public and private outfalls are identified and mapped within the Town of Oro Valley’s Cartegraph/GIS database. This process is ongoing and continuous. Measurable goals for this BMP shall be the mapping of all waters of the United States listed in AAC R18-11 Appendix B, as well as all outfalls discharging to those protected waters. BMP 3.4 Annual Municipal Employee Illicit Discharge Training Program SWU staff will help facilitate detection and prevention of illicit discharges and connections to the MS4 through annual education and training of Town staff on potential sources and hazards associated with these illicit activities. This training includes participants learning to identify sectors of the Town (by region, industry, neighborhood), most likely to contribute illicit discharges, and to use this information to perform their job duties more effectively. The measurable goal for this BMP shall be the number of Town employees annually trained in the detection, elimination and reporting of illicit discharges and connections to the Town’s MS4. 10 October 31, 2021 BMP 3.5 Training of Town Volunteers SWU staff train all volunteers participating in the Adopt-a-Wash, Adopt-a-Road, and Adopt-a-Trail programs to conduct dry-weather inspections. Staff instruct new and returning volunteers on the importance of water quality and the elimination of non-stormwater discharges. The measurable goal for this BMP shall be the number of Town volunteers receiving this training annually. BMP 3.6 Written IDDE Procedures The objective of this program is to minimize the discharge of pollutants to the maximum extent practicable, by detecting, investigating and resolving illegal dumping and disposal of unpermitted, non-stormwater flows in the Town’s stormwater drainage system including pipes, gutters, swales, and other conveyance infrastructure. The Town of Oro Valley has drafted and implemented an illicit discharge detection and elimination (IDDE) program to be used in the detection, investigation and elimination of illicit discharges to the MS4. The measurable goal for this BMP shall be an official written procedure on the detection, elimination, and effective enforcement response to illicit discharges within the Town of Oro Valley. MCM-4 Construction Site Stormwater Run-Off Control SWU staff have helped to develop Town procedures for plan review, site inspection, and stormwater enforcement at construction sites. Targeted construction sites are those that result in the disturbance of one or more acres, and those disturbing less than one acre if those activities are part of a larger common plan of development or sale with an overall planned area of disturbance equal to or greater than one acre. Other targeted construction sites will include those occupying less than one acre, but including within the disturbed area a wash or part of a wash that may be disturbed or impacted during development. Targeted pollutants from construction sites include, but are not limited to: sediment, paint, oil and grease, debris, and chemicals such as those contained within concrete washout water. SWU staff actively manage stormwater runoff control through the enacted Stormwater Utility Ordinance, Town Code 15-24, the Town of Oro Valley Department of Public Works Drainage Criteria Manual (2010), site-specific drainage reports, and a SWPPP management program. Additionally, the Town’s Drainage Criteria Manual contains specific language addressing erosion and sediment control, and serves to drive standard operating procedure in enforcement. Stormwater Utility Ordinance, 15-24-14, gives the Town authority to manage and impose penalties on any new construction that does not adhere to ADEQ Construction General Permit Requirements. SWU staff have adopted six BMP’s as primary methods and means for enforcing construction site run-off control. BMP 4.1 Comprehensive Pre-Construction Site Plan Review Every applicant for a building permit, or grading permit for activities that disturb one acre or more, or those disturbing less than one acre (if those construction activities are part of a larger common plan of development that will disturb one acre or more), are required to adhere to the State of Arizona Construction General Permit, and to submit a project-specific Stormwater Pollution Prevention Plan (SWPPP) for Town approval. The Town utilizes its Plan Review Distribution, Type 1 Grading Permit Checklist and Type 2 Grading Permit Checklist to ensure all review processes are fully executed. (These checklists are provided in Attachment H, Items 3 – 5.) During pre-construction meetings with developers and contractors, SWU representatives explain project BMP requirements and detail requisite information to be provided by the developer to the Town upon project commencement. The Town requires developers to submit copies of the NOI and the SWPPP prior to site grading. The Town also requires notification of SWU personnel when any changes are made to project SWPPP’s. Part of this notification process is submission of plans reflecting these changes. Notification of SWU staff is required when a new SWPPP associated with a new contractor or project phase has taken precedent. 11 October 31, 2021 Attendees of these pre-construction meetings will be informed of the above Town procedures and requirements, as well as the occurrence of routine onsite SWPPP inspections. (Attachment H, Item 5 depicts the agenda items that are utilized to guide pre-construction meetings.) The Town utilizes a checklist to assess the developer’s plans. A grading permit will not be issued by the Town without ADEQ confirmation of receipt of NOI. The measurable goal for this BMP shall be the number of plans reviewed which require the submittal of a stormwater pollution prevention plan. BMP 4.2 Erosion and Sediment Control for Capital Improvement Projects SWU staff works to eliminate the discharge of pollutants through support and facilitation of proper management of capital projects executed by the Town. These projects include the construction of new public streets and sidewalks, parks, trails, facilities, or utilities (water mains, traffic lights, and stormwater management infrastructure) constructed, demolished or modified by the Town. The measurable goal for this BMP shall be the proper implementation of sediment, erosion and waste controls for every Town of Oro Valley capital improvement project. BMP 4.3 Establishment and Review of Town Ordinances Regarding Disposal of Hazardous Construction Site Waste, Sediment Control, and Erosion Control For the purposes of continued compliance with EPA and Arizona State General Permit regulations, SWU staff have established, and will review as necessary, specific ordinances regarding hazardous waste disposal and sediment and erosion control at construction sites. According to Town procedure, each ordinance proceeds through public review and requires approval by the Mayor and Town Council. Ordinances will include language allowing for applicable penalties in the event of non-compliance on the part of responsible parties. The measurable goal for this BMP shall be annual review of existing ordinances and revision or development of ordinances as necessary, in order to ensure ongoing compliance with the Arizona State General Permit (AZG2021-002) adopted September 30, 2021. BMP 4.4 Documentation of Procedures SWU staff have developed, and will continue to assess, written procedures for tracking and archiving all final site plan submittals and inspection documents associated with construction site SWPPP’s and SWPPP inspections, including required remedial actions, for a period of three years after project completion date. SWU staff have also developed written protocols pertaining to SWPPP inspections conducted by SWU staff on construction sites. The measurable goals for this BMP shall be an official up to date standard operating procedure on SWPPP inspection protocols, as well as an up to date inventory of all construction sites with appurtenant documents throughout Town. BMP 4.5 Personnel Qualifications and Education of Private Contractors/Developers All SWU field staff are certified stormwater inspectors, and are able to assess construction sites within the Town of Oro Valley, for compliance with the State of Arizona Construction General Permit. During pre- construction meetings all site operators are notified by Stormwater Utility staff of the specific expectations regarding erosion, sediment, and waste control on construction sites. This process is done by both verbally expressing the Town of Oro Valley’s expectations of SWPPP operators during the construction phase as well as a brochure that is given to contractors during these meetings. This brochure explicitly outlines Town of Oro Valley expectations throughout all phases of construction including what is expected upon completion of the project and these developments are transitioned into the post-construction phase. The measurable goal for this BMP shall be the number of hours spent by the Town of Oro Valley, educating contractors and developers on erosion, sediment and waste control at construction sites each reporting year. 12 October 31, 2021 BMP 4.6 Establish Procedures for Receipt and Consideration of Constituent Submittals Oro Valley solicits public information through both the SWU office and the town’s Constituent Services Coordinator (CSC). The Stormwater Engineer and CSC are the principal contacts for constituent concerns, and they coordinate on situational assessment and potential resolution. Current means of information transfer include e-mail, telephone calls, direct conversations, and a web-based reporting system. The measurable goal for this BMP shall be maintaining these avenues by which the public may express concerns about water quality issues on construction sites, as well as logging of, and expeditious investigation of all constituent concerns. MCM-5 Post-Construction Runoff Control The SWU’s policies provide for the reduction of pollutants discharged to the MS4 from development and redevelopment projects; target pollutant discharge is equal to or less than discharge from conditions prior to project commencement. Town Code 15-24, in partnership with the Town’s Drainage Criteria Manual, 2020 edition, provide the basis by which SWU staff comply with and enforce EPA-mandated post-construction pollution control regulatory requirements. BMP 5.1 Creation, Review and Enforcement of Post-Construction Stormwater Pollution Prevention Regulatory Mechanisms and Standard Operating Procedures Town Code 15-24 gives the Town authority to regulate and impose penalties on any development site not in compliance with SWU requirements, established in compliance with EPA- and ADEQ-mandated post- construction stormwater pollution prevention guidelines. The Town requires permanent ground stabilization where applicable, as well as all new commercial development sites to install and maintain first flush filtration devices on all newly created, privately held drainage infrastructure where applicable. Town Code 15-24 provides the SWU opportunities to perform routine inspection of privately owned pollution control measures in order to ensure proper functioning and appropriate maintenance. This ordinance was designed to include an escalating corrective approach to violations detected by the SWU. The Town also observes standard operating procedures for site plan review and site inspection during and after construction to ensure impact to the MS4 is at or less than pre-construction levels. A standard item on each pre-construction meeting agenda outlines certain requirements and procedures utilized by the Town with regard to post-construction pollution prevention. Written acknowledgement, and agreement with these requirements and procedures is requisite for developers to commence construction activities. All private site structural controls in place at new developments require certification by a professional engineer for building and installation. Furthermore, developers are informed at pre-construction meetings that the SWU requires submission of the Notice of Termination (NOT) and an ESRI shapefile of new MS4 infrastructure associated with each project upon completion. Upon receipt of the project-associated ADEQ NOT, SWU staff establish a post-construction site inspection schedule based on NOT date and rain events with the site developer. In addition, construction site developers are responsible for post-construction SWPPP controls for one year after the NOT date. SWU staff conduct routine and weather-related site inspections throughout the first year of post-construction activities. Compliance with these requirements is a prerequisite for post-construction release of assurances and associated fees. The measurable goal for this BMP shall be the number of post- construction site inspections conducted during each reporting year. 13 October 31, 2021 BMP 5.2 Comprehensive GIS Inventory of Active and Finished Construction Projects The Town of Oro Valley has and continues to update and keep accurate, a map of construction projects within the Town. Once a notice of termination is acquired or a final SWPPP inspection is conducted for a project, that project is marked project finished in the GIS database. Finished projects are then moved into the post- construction inspection phase, and inspected for efficacy with regard to local, state, and federal water quality standards. The measurable goal for this BMP will be an ongoing and continuous, up to date inventory of construction sites in post-construction phase. BMP 5.3 Implement Standard Operating Procedure on Post-Construction Inspections The Town of Oro Valley has drafted a standard operating procedure on post-construction inspections, and schedules them based on either the date of Termination for the project or the date of the final SWPPP inspection for projects that don't require a NOI. This procedure has helped the Town schedule inspections in the post-construction phase. This program assists in alerting property owners/developers to problems associated with post-construction stormwater control mechanisms. The purpose of the post-construction inspection procedure includes the following: A reduction in the discharge of pollutants, to the maximum extent practicable, to the MS4 permit area by completed construction projects. This is done through verification of the following: 1. Post construction site planning procedures are implemented and will reduce impacts to stormwater quality. 2. Structural and non-structural control measures are implemented, and all temporary best management practices (BMPs) have been removed. 3. All post construction activities are operating in compliance with Town of Oro Valley code. Post construction inspections are performed in accordance with the Arizona Department of Environmental Quality (ADEQ) small MS4 permit AZG2021-002 requirements found in section 6.5. The measurable goals for this BMP shall be maintaining an effective post-construction inspection protocol for all completed projects, as well as the number of post-construction inspections performed each reporting year. BMP 5.4 Site Plan Reviews Included in the Town of Oro Valley plan review process is assessment of new drainage infrastructure design for efficacy with regard to local, state, and federal water quality standards. The Town of Oro Valley routinely inspects construction/building sites, making sure the approved plans are adhered to during the construction phase. The Town notifies developers in the event of non-compliance with Town permitting ordinances/processes. The measurable goal for this BMP shall be continued maintenance of a site plan review process for all public and private construction projects within the Town of Oro Valley. MCM-6 Pollution Prevention and Good Housekeeping for Municipal Operations The SWU works to minimize or eliminate the discharge of pollutants through the proper operation and maintenance of the public MS4, public streets, municipal parking lots, and municipal equipment yards. Seven best management practices are now being employed by the Town to facilitate stormwater pollution prevention and good housekeeping. 14 October 31, 2021 BMP 6.1 Inspection of Town of Oro Valley Municipal Operations, Storage, and Maintenance Facilities The Town of Oro Valley will conduct inspections every quarter of every reporting year at the operations and maintenance yards located at 680 W. Calle Concordia, and 10700 N. La Canada Dr. The Town of Oro Valley will conduct inspections annually at the JDK Park Aquatic Center and the Community Recreation Center. Town of Oro Valley Stormwater Utility staff will inspect these Chemical storage and material handling areas and all existing onsite BMPs for conformance to NPDES Phase II permit requirements. Any identified deficiency will be corrected and documented per NPDES Phase II standards. The measurable goal of this BMP shall be the number of inspections of Town facilities conducted during each reporting year. BMP 6.2 Street Sweeping The SWU works in cooperation with the Operations Division to minimize storm sewer system pollutants through the removal of organic material, sediment, and debris from Town streets. Major streets are scheduled to be swept quarterly and residential streets are scheduled to be swept twice each year. Town Operations Division staff perform sweeps with proper equipment that is regularly maintained per specified Town of Oro Valley maintenance procedures. The measurable goal for this BMP shall be the amount of material removed from the Town MS4 through this program each reporting year. BMP 6.3 Implementation of SPCC and Operation and Maintenance Plans for Town Maintenance Facilities The Town of Oro Valley has developed spill prevention, control and countermeasure (SPCC) plans, as well as operation and maintenance (O&M) plans for both Town owned municipal operations and maintenance yards. These plans meet all Federal, State, and Local requirements for procedures on equipment and material handling, maintenance and storage procedures as well as the fundamental steps in prevention, control, cleanup and reporting of onsite hazardous chemical spills. The measurable goal for this BMP shall be continued adherence (verified through quarterly inspection) to these site-specific plans throughout each reporting year during this permit cycle. BMP 6.4 Municipal Employee Training Program The Town of Oro Valley Stormwater Utility staff will conduct annual pollution prevention, good housekeeping, and spill prevention/response training sessions for all Town municipal operations division, and parks and recreation employees. The measurable goal for this BMP shall be the number of Town staff trained on stormwater pollution prevention and good housekeeping annually. BMP 6.5 Town of Oro Valley Municipal Vehicle and Heavy Equipment Washing Procedures The Wastewater from vehicle or equipment cleaning performed outdoors can contribute toxic hydrocarbons and other organic compounds, oils and greases, nutrients, phosphates, heavy metals and suspended solids to stormwater. The Town of Oro Valley utilizes an onsite industrial grade vehicle and heavy equipment washing area that recycles the vehicle wash water and collects all potential environmental contaminants for proper disposal. The Town of Oro Valley has utilized these equipment washing procedures since the installation of this equipment in 2011. The measurable goal for this BMP shall be quarterly inspections of this equipment to ensure proper maintenance and functionality. BMP 6.6 Town of Oro Valley Fleet Maintenance Schedule The Town of Oro Valley adheres to a fleet maintenance schedule designed to prevent adverse effects to the environment due to lack of regular vehicle and heavy equipment maintenance. The Town of Oro Valley vehicle maintenance schedule includes an escalated maintenance regimen based upon mileage for vehicles and engine hours for heavy equipment. For vehicles the schedule is as follows: Every 5000 miles (A service), every 15 October 31, 2021 10000 miles (A service plus B service), Every 20000 miles (A service plus B service plus C service). For heavy equipment the schedule is as follows: Every 250 hours (A service), Every 500 hours (A service plus B service), Every 1000 hours (A service plus B service plus C service), Every 2000 hours (A service plus B service, plus C service, plus D service). The measurable goal for this BMP shall be documented service records (Cartegraph records) following this maintenance schedule for all Town owned heavy equipment and vehicles. BMP 6.7 Facility Safety Data Sheet Inventory The Town of Oro Valley keeps a comprehensive safety data sheet inventory of all potentially hazardous materials utilized onsite at the two operation and maintenance facilities located at 680 W. Calle Concordia, and 10700 N. La Canada Dr. Each safety data sheet includes a section on accidental release measures, providing information on the appropriate response to spills, leaks, or releases, including containment and cleanup practices to prevent or minimize exposure to people, properties, or the environment. It also includes recommendations distinguishing between responses for large and small spills where the spill volume has a significant impact on the hazard. The information in these sheets consists of recommendations for:  Methods and materials used for containment (e.g., covering the drains and capping procedures).  Cleanup procedures (e.g., appropriate techniques for neutralization, decontamination, cleaning or vacuuming; adsorbent materials; and/or equipment required for containment/clean up) The measurable goal for this BMP shall be a continuously updated safety data sheet inventory of hazardous materials stored at these two locations within the Town. III. MONITORING Analytical monitoring is required by MS4’s that discharge to outstanding waters or impaired waters listed in section 303(d) of the Federal Clean Water Act. At this time the Town does not discharge to any listed outstanding or 303 d impaired waters, and the Town’s SWMP does not include provision for analytical stormwater monitoring. IV. SWMP EVALUATION AND REVISION SWU staff will review the SWMP in June of each year to evaluate the implementation status of the SWMP components, the effectiveness of each component, and the interaction between various components. During the annual review, the Town determines if revisions to the SWMP are required and appropriate. If SWMP revisions or additions are needed, the Town notifies ADEQ of any changes to the SWMP. If components of the SWMP need to be altered, the Town submits the proposed revisions to ADEQ with an explanation of why the original practice was ineffective and how the alterations will better address the goals of the management practice. V. SWMP REPORTING AND PROGRAM ASSESSMENT Annual Report: To comply with Arizona State General Permit section 8.3, the Town submits annual reports on or before September 30th of each year for the preceding period of July 1 through June 30. The annual report summarizes the following: • The status of self-evaluated compliance with permit conditions, an assessment of the appropriateness of the identified BMPs, progress towards achieving the goal of reducing the discharge of pollutants to the maximum extent practicable and protecting water quality, and the measurable goals for each of the MCM’s; • Results of any information collected and analyzed; 16 October 31, 2021 • Changes made to the SWMP since the last annual report and a summary of stormwater activities the Town plans to undertake during the next reporting period; • Proposed changes or updates to the SWMP; • A description of BMP’s to be implemented within new areas annexed over the past year located within the regulated boundaries of the MS4; • A description and schedule for implementation of additional BMP’s that may be necessary; and • If necessary, notice that the Town is relying on another government entity to satisfy some of the permit obligations.

Signed:____________________________________ Date:___________________________ Printed:___________________________________ Attachment F: Illicit Discharge Detection and Elimination System. 1 Illicit Discharge Detection and Elimination Program Introduction This Illicit Discharge Detection and Elimination (IDDE) Program describes procedures and best management practices to protect the Town of Oro Valley’s Municipal Separate Storm Sewer System (MS4) from pollutants due to illicit discharges and illegal connections. This Program complies with requirements in Section 6.3 of the Arizona Department of Environmental Quality AZDEQ Permit (AZG2021-002) “Arizona Pollutant Discharge Elimination System General Permit for Stormwater Discharges from Small Municipal Separate Storm Sewer Systems to Waters of the United States” which states: “The permittee shall implement an IDDE program to systematically find and eliminate sources of non- stormwater to its municipal separate storm sewer system and to implement procedures to prevent illicit connections and discharges.” Legal Authority The purpose and intent of this IDDE Program is to ensure the health, safety, and general welfare of citizens, and protect and enhance the water quality of watercourses and water bodies in a manner pursuant to, and consistent with, the Federal Clean Water Act (33 U.S.C. 1251 et seq.), National Pollutant Discharge Elimination System Regulations (40 CFR Part 122), and State regulations for stormwater discharge (ARS Title 49, Chapter 2, Article 3.1) by establishing minimum stormwater management requirements for the management of pollutants that are, or may be, discharged to the municipal storm sewer system. Authority for this Program is the “Storm Water Quality Management and Discharge Control Ordinance” described further in Town Code Chapter 15-24. IDDE Program Responsibilities The Town of Oro Valley Stormwater Utility Staff is responsible for development and implementation of this program. Table 1 below identifies key Town of Oro Valley staff and contact information for those who will implement the IDDE program. Table 1. Town of Oro Valley Stormwater Utility IDDE System Implementation Staff. Position IDDE Program Responsibility Phone Stormwater Utility Division Manager Program Control & Oversight 520-229-4816 Sr. Stormwater Engineer Program Administration 520-229-4816 Stormwater Utility GIS Analyst Investigation/Record Keeping 520-229-4816 Stormwater Utility Inspector Investigation/Record Keeping 520-229-4816 2 Illicit Discharge Reporting A) Training of municipal employees. The TOV will help facilitate detection and prevention of illicit discharges and connections to the MS4 through education and training of Town staff on potential sources and hazards associated with these illicit activities. Selected staff are trained as Certified Stormwater Inspectors by the National Stormwater Center or equivalent (we currently have 13). This training includes identifying sectors of the public (by region, industry, neighborhood), most likely to contribute illicit discharges, and to use this information to perform more effective inspections. The Town of Oro Valley also annually trains every municipal Operations and Maintenance employee in detection and reporting of illicit MS4 activity to the Stormwater Utility. B) Solicitation of public reporting of illicit MS4 activity. The TOV solicits public information and reporting of illicit discharges through both the SWU office and the Town’s Constituent Services Coordinator (CSC). The Stormwater Utility manager and CSC are the principle contacts for constituent concerns, and they coordinate on situational assessment and potential resolution. Current and future means of information retrieval include e-mail, telephone calls, letters, direct conversations, and a web-based reporting system. C) Internal Procedure When an Illicit Discharge is Reported or Discovered. Each time an illicit discharge is reported, Town Staff will immediately determine what type of discharge has occurred and whether it poses an immediate threat to public health or the environment. The following considerations are made upon discovery of an illicit discharge. • What type of spill or discharge has been discovered? • How much material has been released? • Does the discharge involve a hazardous material and should the fire department or other emergency responders be notified? • Is there imminent danger of this discharge or spill rapidly spreading to sensitive environmental areas? • Should other agencies be notified? Table 2. State, County and National Agency Contacts for Illicit Discharges. Agency Phone Number When To Contact Arizona Department of Environmental Quality 1-800-234-5677 When a discharge is an acute public health threat involving extremely hazardous material. Arizona Department of Transportation (ADOT) 1-800-251-5866 When a suspected discharge originates from or enters areas of ADOT responsibility. Pima County Department of Environmental Quality 520-724-7400 When a suspected discharge originates from or enters into Unincorporated Pima County. 3 U.S. Environmental Protection Agency/911 1-800-424-8802/ 911 When a discharge is an acute public health threat involving extremely hazardous material. When an Illicit discharge is either reported to, or discovered by, staff, the internal procedure for documenting, investigating, and eliminating such discharges is as follows. The Stormwater Utility Division Manager will upon reporting or discovery of an illicit discharge, dispatch an inspector for further investigation of the incident, and, if necessary, report the incident to the proper external agencies (see table 2. above). The inspector, upon arrival at the location, will determine the source and whether the source is public or private. The Stormwater Utility Analyst will map the incident and retain all records associated with the incident in the proper Drainage Violation folder. If the source of the illicit discharge is public, the Stormwater Utility Division Manager will coordinate with Town of Oro Valley municipal operations staff to eliminate the discharge as quickly as possible. If the source of the discharge is private, a drainage violation will be issued by the Stormwater Utility Division Manager that clearly outlines a schedule for cessation of the discharge as well as requiring statement acknowledging responsibility and confirming future compliance with all Town of Oro Valley requirements and codes dealing with the discharge of illicit substances. If issuing a civil penalty becomes necessary as a result of an illicit discharge, the Town of Oro Valley has in place a water quality ordinance (Town of Oro Valley Code 15-24) and an enforcement response plan (see appendix A of this document) to bring potential violators in compliance with federal, state, and local regulations. Identifying Potential Town of Oro Valley Illicit Discharge Hotspots. The Town of Oro Valley has identified priority areas most likely to have illicit discharges or connections. This information helps field staff and managers decide where to conduct detailed field investigations to pinpoint and eliminate illicit discharges and connections. The process includes reviewing information contained in the Town’s Cartegraph/GIS database, gathering staff knowledge of the Town’s watersheds, determining where illicit discharges have been reported in the past, and compiling other information collected by field crews. The following section describes priority areas already identified for future illicit discharge investigations, as well as procedures that staff uses to conduct a more detailed office assessment if needed. A) Priority Areas Identified. The Town of Oro Valley has identified three main priority areas where illicit discharges have a higher likelihood of occurring. These include: • The commercial corridor of State Highway 77 (Oracle Road.) from Ina Road. to Rancho Vistoso Boulevard. • The commercial and industrial corridor of East Innovation Park Drive. • The Commercial corridor of North La Canada Drive, between Lambert Lane and Naranja Drive. Within these priority areas, the Town of Oro Valley will investigate businesses or activities that typically generate wastes that may contain fecal coliform bacteria, petroleum products, heavy metals, oil and grease, and soapy washwater. The Town will conduct unannounced site inspections, public education and outreach, and follow-up investigations at: 4 • Businesses that generate pet waste (e.g., veterinary clinics, pet boarding centers, pet stores, and animal shelters) and public parks. • Automotive service centers and gas stations. • Restaurants. • Grocery stores and commercial retailers. • Light industrial and manufacturing facilities. • Horticultural and plant nursery facilities. Figure 1 below shows areas within the Town of Oro Valley where illicit discharges have a moderately higher likelihood of occurring. 5 B) Field Assessment in These Priority Areas. Detailed procedures for field assessments are discussed in the Town of Oro Valley standard operating procedure for outfall inspection titled Dry and Wet Weather Field Screening of Outfalls (appendix B of this document). Information collected during dry weather outfall inspections (e.g., outfalls where suspected or obvious illicit discharges are discovered) are used to identify priority areas where follow-up investigations need to be pursued. Information collected during routine MS4 asset inspections, health department inspections, and water quality monitoring are also used to identify priority areas for future investigation. Maps are prepared to assist with field assessment in these priority areas and include include the following information. • Nearby washes • Streets • Landmarks • Aerial photography • Major land uses • MS4 network assets Eliminating Illicit Discharges. Upon detection of an illicit discharge, the Town of Oro Valley will identify all responsible parties and eliminate those discharges as expeditiously as possible through every legal avenue at the Town’s disposal. When immediate elimination of an illicit discharge is not possible the Town of Oro Valley will establish a schedule of elimination to expedite the removal of the discharge to the maximum extent practicable. A report on discharge location, discharge volume, dates the discharge took place, responsible parties, and mitigation techniques will be provided annually to ADEQ as part of the Town of Oro Valley annual MS4 report. Visual Monitoring. The Town of Oro Valley has developed and implemented a visual monitoring program of municipal outfalls. Included in this monitoring program are parameters for identification of illicit discharges during both dry weather and wet weather inspection of municipal outfalls. Outfall inspection during dry and wet weather includes records of: • Outfall identification • Personnel conducting the inspection • Time and date • Weather conditions at the time of inspection • Estimated flow rate (if applicable) • Apparent odor, color, and clarity of the water (if applicable) • The presence of floatables and other debris (if applicable) • Condition of the ground during dry weather inspection • Recording of nearby land use A) Visual Dry Weather Outfall Monitoring. The Town of Oro Valley has developed a standard operating procedure titled Dry and Wet Weather Field Screening of Outfalls, which clearly outlines municipal outfall inspection procedures. 6 B) Visual Stormwater Discharge Monitoring. The Town of Oro Valley has identified 5 major outfalls strategically chosen for their close proximity to dense commercial and urban residential land use. These outfalls will be monitored at a minimum of four times per year (twice during storm events each rainy season). Procedures for monitoring outfalls during storm events are clearly outlined in the Town of Oro Valley municipal outfall identification and inspection standard operating procedure titled Dry and Wet Weather Field Screening of Outfalls. Indicators of IDDE Program Progress An important component of the IDDE program is a tracking and reporting system. A summary of the information collected for the tracking and reporting system will be included in the annual report to Arizona Department of Environmental Quality. The information stored in the tracking and reporting system will be evaluated on an annual basis at a minimum to adjust the IDDE program as needed. The Town of Oro Valley currently uses Cartegraph and GIS software to store and analyze data and produce maps. The following information should be tracked and reported in Cartegraph\GIS to assist with annual report preparation and program evaluation. • Number of illicit discharge complaints received from the public • Feedback received from public education efforts • Percentage of the Town wide MS4 mapped • Results of field assessments in high priority areas • Number of MS4 assets inspected • Photographic documentation of inspections • Results of follow-up monitoring in problematic areas • Number of illicit connections and discharges discovered and eliminated • Status and efficacy of statutes and enforcement procedures • Dates of staff training • Number of staff trained Appendix A: Town of Oro Valley Illicit Discharge Detection & Elimination System (IDDE) Enforcement Response Plan Introduction: Under the terms of the Arizona Pollutant Discharge Elimination System General Permit for Stormwater Discharges from Small Municipal Separate Storm Sewer Systems (AZG2021-002), the Town of Oro Valley is required to develop and implement adequate enforcement authority for illicit discharges into its Municipal Separate Storm Sewer System (MS4). The purpose of these Enforcement Response Procedures is to communicate how the enforcement tools available to the Town, will be used to achieve compliance. I. Enforcement Response Plan (ERP) Plan Definitions A. The Oro Valley Town Engineer shall be the ERP Administrator. B. The Oro Valley Town Engineer (ERP Administrator) shall authorize in writing a person or person(s) to act as Town of Oro Valley ERP Representatives. C. “Town of Oro Valley ERP Representative” shall refer to any employee or consultant authorized by the ERP Administrator to act under this Enforcement Response Plan. D. “Illicit Discharge”, shall refer to “any discharge to the municipal separate storm sewer system including sediment, which is not composed entirely of storm water, except for discharges allowed under the National Pollutant Discharge Elimination System, or waters used for firefighting operations. E. “Consent Order/Consent Order Agreement” a written agreement permitting the violator to accept responsibility for the discharge and provides the opportunity to voluntarily clean up and/or correct an illicit discharge reducing additional damage and potential penalties associated with cleanup costs. F. “AZPDES Non-Filers”, shall refer to any facility or activity discharging the Town of Oro Valley MS4 without a required AZPDES/NPDES permit. II. AZPDES Non-Filers The Town of Oro Valley maintains a comprehensive GIS inventory of all ongoing construction projects within the Town. Obtained as attachments for this inventory are all associated NPDES/AZPDES notices of intent (NOI) for each project. No project is allowed to commence or operate without a current NOI on file in this system. The Town of Oro Valley will report all suspected non-filers to ADEQ at AZPDES@azdeq.gov every month if there are non-filers to report. This report will include the facility or project name and location of the suspected non-filer. The email subject line will include “Non-filer – Town of Oro Valley MS4”. III. Description of Each Type of Enforcement Response A. Written Warnings 1. Field Compliance order A) A Town representative may observe potential compliance issues in the field. In instances involving potential compliance issues, the Town’s Representative will issue a verbal, and/or written warning. Any written Field Compliance warning may be given verbally or sent either by email or a mailed letter specifying the nature of the violation, the required corrective action and a follow-up inspection date. Failure to cure compliance issues subject to a Field Compliance Order shall result in enforcement escalation. 2. Notice of Violation A) If upon a site inspection, a Town representative observes compliance issues that have resulted in an illicit discharge of pollution, including sediment, the representative will issue: 1. Notice of Violation: a) The notice of violation will specify the nature of the violation, the required corrective action(s), and a follow up inspection date. b) The notice of violation will require the party committing the violation to submit a satisfactory remediation and prevention plan to include specific steps to be taken to prevent further illicit discharges from the site, within 5 days of the date of the violation. c) If the required corrective actions are not completed to the satisfaction of the ERP Administrator by the follow-up inspection date, the appropriate Town representative in consultation with the ERP Administrator will: • Revoke all current building or construction permits where applicable. Revoked permits shall only be reinstated after the permittee has reapplied for a new permit complete with a new permit fee and resulting remediation of all further illicit discharges. • In the event no Town permits have been issued, a Storm Water Violation Citation will be issued. 3. Consent Order/Consent Order Agreement in lieu of Notice of Violation A) A Consent Order will include specific corrective actions to be taken in correcting the illicit or sediment discharge together with a specified time frame to finish the corrective actions. 1. Consent Order Agreements will only be issued to violators that can provide documentation verifying that they or their designated representative are qualified to handle the required illicit discharge cleanup. 2. The ERP Administrator is empowered to enter into Consent Order Agreements with violators on behalf of the Town of Oro Valley. 3. Where the discharge and cleanup area affect private (third party) properties, Consent Orders must be approved by all parties involved or a Notice of Violation will be issued. IV. Violation Procedure A) The ERP Administrator, upon determining the level of violation, will notify the violator by sending either a Written Notice of Violation to their address of record. Notice shall set forth the nature of the violation, the date and time of violation, and the name of the official issuing the notice and spell out the opportunity to work through the matter through a Consent Order Agreement if the violator qualifies. B) Once a Notice of Violation is issued, the alleged violator shall within five business days of the date of issuance of the notice, pay the amount set forth on the schedule of fines for the violation and remediate the violation as provided in this Section. The fine may be paid in person or by mail, and payment shall be deemed to be an admission of the violation. Failure to pay the fine amount or remediate the violation within 14 days shall result in a Summons and Complaint to be filed by the Town Attorney in the Oro Valley Magistrate Court or referral of the violation to the Arizona Department of Environmental Quality “ADEQ “. 5. Cease and Desist Orders A) The Town Administrator may issue a Cease and Desist Order effectively stopping all work on a site where there is a clear violation, a continuing violation, or disregard for: • Town of Oro Valley ordinances regulating the illicit discharge of pollutants or sediment. • ADEQ building or construction storm water permit requirements • Previously issued field compliance orders, notices of violation, or breach of any signed Consent Order Agreement associated with the site where the illicit discharge occurred. B) Cease and Desist orders shall require that the violator must comply with the order and take appropriate remedial or preventive action as is needed to properly address a continuing or threatened violation; including the halting of all operations on the site except for authorized cleanup, termination of any discharge, or the installation of appropriate control measures. C) All Cease and Desist orders serve as a notice of violation with applicable fine and penalties. D) The ERP Administrator in consultation with appropriate Town Representative(s) may suspend, revoke or modify any Town issued permit authorizing a land development project, or any other project of the applicant associated with the violation in question. E) A suspended, revoked or modified permit may be reinstated only after the applicant or designated responsible party has completed the corrective actions set forth in the written Notice of Violation/Cease and Desist Order. F) Violators with outstanding violations shall not receive any new Town of Oro Valley construction or building permits until all outstanding violations have been remedied and all applicable fines and penalties paid. G) Contractors that have had two or more civil penalties within the previous 12 calendar months shall be required to deposit a cash assurance equal to double the assurance amount normally required for each permit obtained. H) In the event violations persist, the Town of Oro Valley may bring legal action to enforce violations issued and to enjoin a continued violation of the Town’s Storm Water code. In the event actions by the ERP Administrator do not result in abatement of any continuing violation the ERP Administrator may request Town Attorney, to begin proceedings in the Oro Valley Magistrate Court where the Oro Valley Magistrate Court is authorized to enforce any civil penalties and/or issue preliminary or permanent injunctions to restrain or compel activities by any violator found responsible. 6. Referrals to ADEQ A) In instances occurring at locations where the Town of Oro Valley has used progressive enforcement to achieve compliance with this ERP where matters do not require immediate action, and in the judgement of the ERP Administrator, these efforts continue to be unsuccessful, in lieu of judicial proceedings the ERP Administrator may refer the violation to the ADEQ. For the purposes of this ERP, “progressive enforcement” shall mean two non-compliant follow-up inspections and two written notices of violation denoting non-compliance. D) The Town of Oro Valley shall keep enforcement files for a minimum of three years after the file is closed, consistent with State of Arizona record retention regulations. V. Penalties A). First offense: $100.00; B). Second offense: $300.00; C). Third offense or subsequent offenses: $500.00.

Town Code Floodplain and Erosion Hazard Management Chapter 17 IV. PROCEDURE Inspection of outfalls is accomplished to ensure that the quality of storm water within Oro Valley is maintained at the highest practiced levels. The Town inspection program consists of semi-annual inspections using the inspection checklist as attached, unless we are notified of a specific discharge incident within the town. There are over 300 outfaIls, comprised of storm water outlets, detention basin outlets, tributary confluences, parking lot discharges, first flush devices, and others. A. Screening Inspection Schedule Outfall inspection will progress in a logical sequence beginning downstream and progressing upstream within channel reaches. The Storm Water Utility goal is to inspect ·every outfall twice per year. Documentation of our Dry Weather Field screening program is utilizing the Cartegraph asset management software program with ArcGIS enterprise GIS geodatabase. B. Citizen Complaints Illicit discharge and dumping complaints will be recorded and investigated within 2 business days. Corresponding outfalls will be identified and the dry weather field screening of outfalls procedures will be followed. If required, proper notifications will be made under the State Emergency Response Program. Customers will receive a response and be kept updated of progress on resolving the complaint. These responses and customer interactions will be properly documented in the incident file. Outfall Inspection Procedures I. Prior to Inspections a. Inspections should not be conducted within 72 hours of a measurable rainfall to avoid confusing accumulated storm water from rain events with true dry-weather discharges. b. Past inspection sheets and photographs for each site should be reviewed in the cartegraph program so the inspector can be aware of the previously noted conditions. c. Blank inspection sheets should be prepared for the upcoming activities (see attached). d. The "Stormwater Test Kit" should be checked to ensure that the instructions, required glassware, and a full stock of reagents are present. Any missing elements should be ordered well in advance of the scheduled time for performing the inspections. Test and calibrate the pH meter to be used. Review all MSDS for the reagents and to ensure proper PPE is available and used. e. Organize the outfall locations to be inspected on a given day into a logical sequence to minimize travel time between sites and backtracking across town. f. Bring the following equipment, at a minimum, to the field when performing the field screening activities: i. Outfall notebook(s) ii. Storm water Test Kit/pH Meter iii. Inspection sheets iv. Camera v. Outreach/Guidance Material vi. GPS Unit vii. Safety Equipment viii. Pens/Pencils ix. Cell phone, flashlight x. Clean Glass Beaker or Bottle II. Inspections a. Travel to and locate the outfall to be inspected. b. Safely access the outfall location. Bear in mind that access to certain sites may be hazardous and require the use of safety equipment or a less direct route. c. If the outfall is located in a densely vegetated wash, extra care should be taken during entry - note that itinerant people often live in such locations in addition to dangerous wildlife. d. Fill out the general information part of the inspection sheet (date, time, inspector, outfall identifier, etc.). e. If a particular outfall has been changed from its original condition, the description of the outfall should be updated on the inspection report. This might include areas where development has occurred and a former dirt channel has been replaced by a drainpipe or riprap channel. If a particular outfall has been completely destroyed or removed, this should be noted on the inspection report and the Inspection Supervisor and the Environmental Project Coordinator notified. An alternate outfall location may need to be established. f. Once at the outfall, the inspector should look for any indication of dry-weather flow or illicit discharges. Such indications include, but are not limited to: i. Flowing water ii. Ponding water or dampness iii. Lush vegetation not characteristic of the surrounding area iv. Unusual Staining v. Deposits of evaporative products (salts) vi. Oil sheen or residual g. Observe and record the condition of the outfall and note any indications that maintenance is needed, such as the presence of significant garbage/refuse, flow obstructions, structural or erosion damage, overgrowth of vegetation, etc. h. Take at least one photograph at each outfall. i. If flowing water is present, the inspector should estimate the f10w rate and record observations with brief descriptions of color, odor, turbidity of the water; oil sheen or surface scum. If there is enough flow to collect a discrete sample, field tests should be conducted and results recorded for: pH; copper, chlorine, detergents, and phenols. If any of the field tests indicate the presence of contamination, a grab sample should be obtained and submitted to an analytical lab under contract to the Town. The parameters to be tested at the lab will be determined by the Storm Water Manager. The inspector should collect another grab sample within a 24-hour period, with a minimum period of four hours between samples. j. If flowing or ponded water is present, investigate to determine the source of the water. This may include searching up gradient in the drainage (inlet grates, catch basins, etc.) for inflows and/or illicit connections, reviewing storm drain maps and records of the area, and interviewing persons who work at possible sources of inflow. k. If the source of the discharge can be established, the inspector should determine if the discharge is allowable under the Town Storm Water Discharge Control Ordinance. Some more common qualifying discharges include: i. Discharges associated with operation and maintenance of the potable or reclaimed water systems, well development, or well monitoring, ii. Residential dechlorinated swimming pool discharges, iii. Discharges from residential coolers and air conditioning condensate, iv. Discharges from residential or charity exterior car washing where only water or biodegradable soaps are used, v. Building or street-wash water where only water or biodegradable soaps are used. l. If the source of the discharge is allowable under the Town's Storm Water Discharge Control Ordinance, and if the results of the field tests are negative, then the discharge is not considered to be a significant source of pollutants. If the source qualifies for the Town's Code and field test results indicate the presence of pollutants, ADEQ should be notified. m. If the source is determined to be irrigation overflow, or a potable or reclaimed line leak, Oro Valley Water should be notified. n. If the source is determined to be residential gray water, notify the discharger that under ADEQ rules, gray water must remain on the discharger's property. Advise the discharger that if the discharge off their property continues, they could be cited under Town of Oro Valley Code and reported to ADEQ for possible further enforcement. o. If the source can be determined and has the potential to be a source of pollutants, as evidenced by field or laboratory testing, it should be considered illicit, and the following steps should be taken to cease the discharge to the storm drain system: discussion with responsible parties, distribution of guidance materials, issuance of a compliance status letter, notice of violation, enforcement action, and notification of regulatory authorities. p. If the source of a dry weather flow cannot be determined, and test results indicate the presence of a pollutant, the inspector should report their findings to the Storm Water Manager for further investigation. Further investigation may include: researching storm drain maps and contributing drainage areas, conducting more extensive field surveys performing a confined space entry into the storm drain, or performing dye tests and other tests to be determined on a case by case basis. q. Any outfall that exhibited flowing or standing water during an inspection should be revisited within at least two weeks from the original inspection date to see if the discharge is continuing or if corrective actions have been effective. Follow-up monitoring of the outfall should be continued on an as needed basis until the dry weather discharge has been eliminated, or until further investigations conclude that the discharge is not a significant source of pollutants. III. After Inspections a. Enter the results of each inspection into ArcGIS/Cartegraph database for the current fiscal year, and file hard copies of photos and inspection sheets in the outfall inspection notebooks. b. Create a work order for the appropriate Department/Division on any field screening location requiring maintenance including areas with significant garbage/refuse, flow obstructions, structural or erosion damage, overgrowth of vegetation, etc. c. Prepare a brief report for any illicit discharges detected, provide flow observations, test results, identify the source (if it can be determined), and list actions taken to stop the discharge. This report will be used to notify appropriate authorities if the discharge continues, or will be summarized in the Annual Report. d.

The process is comprised of: 1. Conceptual Design Review- The intent of conceptual design is to ensure that a project’s overall site layout is functional within its boundaries and is compatible with the surrounding area. Conceptual design requires review by the Planning and Zoning Commission and approval by Town Council. However, if the site plan substantially conforms an approved Tentative Development Plan (within the past 5 years), the applicant may proceed to final design review. 2. Final Design Review-The intent of final design review is to ensure that a project’s final plans are consistent with the conceptual plans approved by Town Council and are consistent with all applicable Zoning Code requirements. Final designs are administratively approved. The Community Development & Public Works Department (CDPW) is here to assist you with your Residential Design Review applications. Throughout the process, you will be working closely with the Town staff to ensure the efficient processing of your application for development. Process Overview: To better understand the approval process for the Town’s Residential Design applications, please refer to the table below. Table of Authority Submittal Type Staff Authority Planning and Zoning Commission Town Council Authority Conceptual Site Plan Review Recommendation Final Decision Conceptual Landscape Plan Review Recommendation Final Decision Final Site Plan Approve No Action Appeal Final Landscape and Irrigation Plan Approve No Action Appeal Native Plant Preservation Plan and Site Resource Inventory* Approve No Action Appeal Recreation Area Plan (if applicable) Approve No Action Appeal *May be approved during the conceptual design phase. 4 Residential Design Review – Process Description Step 1 – Pre-application Meeting Applicants must attend a pre-application meeting with the Development Review Committee (DRC) for a preliminary review of their proposed development to discuss the required process and broad issues related to the proposal. Development Review Committee meetings provide applicants with preliminary feedback from Town Staff and outside reviewers. The typical issues discussed at a DRC meeting include the development process, consistency with adopted plans, zoning provisions (i.e. permitted uses, building setbacks, parking requirements, etc.), engineering, fire and building code requirements. To initiate a pre-application meeting, applicants must submit a written request and preliminary drawings 10 working days prior to the expected meeting date. (Applicants should refer to the Pre - application Conference Process Guide for additional details). The Development Review Committee will send a review letter identifying any broad concerns with the application and the project’s development process within 3 working days following the meeting. IF YOUR SITE PLAN IS IN SUBSTANTIAL CONFORMANCE WITH A REZONING TENTATIVE DEVELOPMENT PLAN APPROVED WITHIN THE LAST 5 YEARS PROCEED TO STEP 7 Step 2 – Neighborhood Meeting Pursuant to Section 22.15 of the Zoning Code, applicants are required to hold at least two neighborhood meetings to provide an opportunity for public participation. The first meeting is an educational session to inform stakeholders of the Town’s process and applicable provisions of the Zoning Code and an opportunity for the applicant to present their project and solicit feedback. The second meeting provides an opportunity for the applicant to present a revised plan and address issues and concerns. The Planning and Zoning Administrator may combine the meetings or request additional meetings as needed. Prior to scheduling the first neighborhood meeting, applicants are required to provide a Public Outreach Plan, in accordance with Section 22.15.D of the Zoning Code, a project fact sheet and any site plans or exhibits intended for the first neighborhood meeting. Once the neighborhood meeting requirements have been satisfied, the applicant shall generate a Public Outreach Report, in accordance with Section 22.15.E of the Zoning Code, to b e submitted with the formal submittal. Step 3 – Formal Submittal Following the first neighborhood meeting, the applicant may submit a formal Conceptual Design package that includes: - Conceptual Site Plan - Conceptual Landscape Plan - Native Plant Preservation Plan and Site Resource Inventory 5 If submitting a conceptual site plan in substantial conformance with an approved Tentative Development (within the past five years), the applicant may proceed to Final Design Review (Section 4.0). To ensure timely review, applicants should review all applicable provisions of the Zoning Code and address the comments of the pre-application review letter. Step 4 – Staff Review After receiving a complete application, staff will review the Conceptual Design application in accordance with the applicable provisions of the Zoning Code, engineering standards and other areas of review authority. A review letter will be sent to the applicant within 20 working days of the submission. The plans may need to be revised and re-submitted for additional reviews to address any remaining comments on the application. When all review comments have been addressed, staff will prepare a report and a recommendation on the application. T he application will be forwarded to the Planning and Zoning Commission for a review. Step 5 – Planning and Zoning Commission (PZC) The Conceptual Design application is reviewed by the PZC within 15 working days of receipt of a staff recommendation. The PZC’s recommendations and decisions are based on the Design Principles outlined in Sections 22.9 and Design Standards, Addendum “A” of the Zoning Code. Planning and Zoning Commission decisions are subject to an appeal by the Town Council. The applicant is expected to present and answer questions during this meeting. Step 6 – Town Council Meeting and Decision The Town Council is the legislative body that makes the final decision to approve, conditionally approve, or deny all Conceptual Design applications. Following PZC recommendation, a staff report is prepared and sent to the Town Council approximately 10 days prior to the Council meeting. The applicant is expected to attend this meeting. Following the meeting, an action letter is sent to the applicant including any final conditions on the request. Step 7 – Proceed to Final Design After receiving an approval from the Town Council, applicants may submit Final Design Plans that addresses any conditions of approval, to CDPW staff for review and approval. Final Design Review Step 8- Formal Submittal Once the conceptual design review process is completed, applicants may submit a formal Final Design Package. Applicants may also submit a formal Final Design Package if the site plan substantially conforms to an approved Tentative Development Plan (within the past 5 years). 6 To ensure timely review, applicants should review all applicable provisions of the Zoning Code and ensure the submittal is complete. Step 9- Staff Review After receiving a complete application, staff will review the Final Design for consistency with the approved conceptual plans and with the applicable provisions of the Zoning Code, engineering standards and all other areas of review authority. A review letter will be sent to the applicant within 20 working days of the submission. The plans may need to be revised and re-submitted for additional reviews to address any remaining comments on the application. When all review comments have been addressed, staff may administratively approve the final plans. Administrative approvals are appealable to Town Council. Step 10- Next Steps Upon approval of the Final Site Plan, a Final Plat is required. Please refer to the Final Plat Process Guide for more information. 7 TOWN OF ORO VALLEY COMMUNITY DEVELOPMENT & PUBLIC WORKS DEPARTMENT 11000 N.

The process is comprised of: 1. Conceptual Design Review- The intent of conceptual design is to ensure that a project’s overall site layout is functional within its boundaries and is compatible with the surrounding area. Conceptual design requires review by the Planning and Zoning Commission and approval by Town Council. However, if the site plan substantially conforms an approved Tentative Development Plan (within the past 5 years), the applicant may proceed to final design review. 2. Final Design Review-The intent of final design review is to ensure that a project’s final pl ans are consistent with the conceptual plans approved by Town Council and are consistent with all applicable Zoning Code requirements. Final designs are administratively approved. The Community and Economic Development Department is here to assist you with your Design Review applications. Throughout the process, you will be working closely with the Town staff to ensure the efficient processing of your application for development. Process Overview: To better understand the approval process for the Town’s Commercial Design applications, please refer to the table below. Table of Authority Submittal Type Staff Authority Planning and Zoning Commission Town Council Authority Conceptual Site Plan Review Recommendation Final Decision Conceptual Landscape Plan Review Recommendation Final Decision Final Site Plan Approve No Action Appeal Final Landscape and Irrigation Plan Approve No Action Appeal Final Rainwater Harvesting Plan Approve No Action Appeal Native Plant Preservation Plan and Site Resource Inventory* Approve No Action Appeal *May be approved during the conceptual design phase. 4 Commercial Design Review – Process Description Step 1 – Pre-application Meeting Applicants must attend a pre-application meeting with the Development Review Committee (DRC) for a preliminary review of their proposed development to discuss the required process and broad issues related to the proposal. Development Review Committee meetings provide applicants with preliminary feedback from Town Staff and outside reviewers. The typical issues discussed at a DRC meeting include the development process, consistency with adopted plans, zoning provisions (i.e. permitted uses, building setbacks, parking requirements, etc.), engineering, fire and building code requirements. To initiate a pre-application meeting, applicants must submit a written request and preliminary drawings 10 working days prior to the expected meeting date. (Applicants should refer to the Pre - application Conference Process Guide for additional details). The Development Review Committee will send a review letter identifying any broad concerns with the application and the project’s development process within 3 working days following the meeting. IF YOUR SITE PLAN IS IN SUBSTANTIAL CONFORMANCE WITH A REZONING TENTATIVE DEVELOPMENT PLAN APPROVED WITHIN THE LAST 5 YEARS PROCEED TO STEP 7 Step 2 – Neighborhood Meeting Pursuant to Section 22.15 of the Zoning Code, applicants are required to hold at least two neighborhood meetings to provide an opportunity for public participation. The first meeting is an educational session to inform stakeholders of the Town’s process and applicable provisions of the Zoning Code and an opportunity for the applicant to present their project and solicit feedback. The second meeting provides an opportunity for the applicant to present a revised plan and address issues and concerns. The Planning and Zoning Administrator may combine the meetings or request additional meetings as needed. Prior to scheduling the first neighborhood meeting, applicants are required to provide a Public Outreach Plan, in accordance with Section 22.15.D of the Zoning Code, a project fact sheet and any site plans or exhibits intended for the first neighborhood meeting. Once the neighborhood meeting requirements have been satisfied, the applicant shall generate a Public Outreach Report, in accordance with Section 22.15.E of the Zoning Code, to be submitted with the formal submittal. Step 3 – Formal Submittal Following the first neighborhood meeting, the applicant may submit a formal Conceptual Design package that includes: - Conceptual Site Plan - Conceptual Landscape Plan - Conceptual Public Art (see Public Art Process Guide for more information) - Conceptual Architecture (see Commercial Architecture Process Guide for more information) 5 - Native Plant Preservation Plan and Site Resource Inventory If submitting a site plan in substantial conformance with an approved Tentative Development (within the past five years), may proceed to Final Design Review (Step 7 and Section 4.0). To ensure timely review, applicants should review all applicable provisions of the Zoning Code and address the comments of the pre-application review letter. Step 4 – Staff Review After receiving a complete application, staff will review the Conceptual Design application in accordance with the applicable provisions of the Zoning Code, engineering standards and other areas of review authority. A review letter will be sent to the applicant within 20 working days of the submission. The plans may need to be revised and re-submitted for additional reviews to address any remaining comments on the application. When all review comments have been addressed, staff will prepare a report and a recommendation on the application. T he application will be forwarded to the Planning and Zoning Commission for a review. Step 5 – Planning and Zoning Commission (PZC) The Conceptual Design application is reviewed by the PZC within 15 working days of receipt of a staff recommendation. The PZC’s recommendations and decisions are based on the Design Principles outlined in Sections 22.9 and Design Standards, Addendum “A” of the Zoning Code. Planning and Zoning Commission decisions are subject to an appeal by the Town Council. The applicant is expected to present and answer questions during this meeting. Step 6 – Town Council Meeting and Decision The Town Council is the legislative body that makes the final decision to approve, conditionally approve, or deny all Conceptual Design applications. Following PZC recommendation, a staff report is prepared and sent to the Town Council approximately 10 days prior to the Council meeting. The applicant is expected to attend this meeting. Following the meeting, an action letter is sent to the applicant including any final conditions on the request. Step 7 – Proceed to Final Design After receiving an approval from the Town Council, applicants may submit Final Design Plans that addresses any conditions of approval, to CED staff for review and approval. Applicants may also submit a formal Final Design Package if the site plan substantially conforms to an approved Tentative Development Plan (within the past 5 years). A final design package includes: - Final Site Plan - Final Landscape and Irrigation Plan - Final Rainwater Harvesting Plan - Final Architecture (see Commercial Architecture process guide for additional information) - Public Art (see Public Art process guide for additional information) 6 To ensure timely review, applicants should review all applicable provisions of the Zoning Code and ensure the submittal is complete. Step 8- Staff Review After receiving a complete application, staff will review the Final Design for consistency with the approved conceptual plans and with the applicable provisions of the Zoning Code, engineering standards and all other areas of review authority. A review letter will be sent to the applicant within 20 working days of the submission. The plans may need to be revised and re -submitted for additional reviews to address any remaining comments on the application. When all review comments have been addressed, staff may administratively approve the final plans. Administrative approvals are appealable to Town Council. Step 9- Next Steps Upon approval, all associated final design plans must be processed with Pima County Addressing for annotation.

PURPOSE A stormwater Construction Site Inspection Program is a program developed for the purpose of tracking, inspecting, and enforcing Federal, State and Local stormwater requirements within construction sites. Inspections to monitor stormwater compliance should be performed at least once per month at each active construction site. Each active project shall be inspected a minimum of 3 times during the duration of the project. For projects with a history of non- compliance a more frequent inspection cycle will be necessary. This Standard Operating Procedure (SOP) describes the major components of the Town of Oro Valley construction site Stormwater Pollution Prevention Plan (SWPPP) Inspection best practices, as well as procedures for evaluating compliance and efficacy of stormwater control measures implemented within and around construction sites. 2. DISTRIBUTION Public Works Stormwater Utility field personnel. 3. PROCEDURE This procedure will be used to guide stormwater field staff through all components of an Arizona Department of Environmental Quality (ADEQ) mandated SWPPP inspection. 3.1 INVENTORY OF ACTIVE CONSTRUCTION SITES For the purposes of inspection planning and data management, all active SWPPPs within the Town of Oro Valley shall be created and maintained by the Stormwater Utility within Cartegraph as SWPPP assets. This database functions as a tracking system and project inventory. Links to project specific SWPPPs, NOIs, inspection records, and project contacts are all stored within this inventory. The idea behind this database is to assist the inspector in prioritizing the daily inspections based on parameters such as project size, slope, previous inspection dates and compliance history. 3.2 SWPPP REVIEW CRITERIA SWPPP plans that are submitted to the Town of Oro Valley for approval will have a review process to guarantee that erosion and sediment control standards and post-construction stormwater standards will be met. 60-03 SWPPP-Inspection-SOP Page 2 Process a. The Town of Oro Valley Stormwater Utility staff will review SWPPP plans. b. A checklist (Appendix A) will be used to ensure accuracy, and efficacy of submitted SWPPPs. c. The Town of Oro Valley will be responsible for enforcement of their stormwater rules. 3.3 CONDUCTING AN INSPECTION The attached Construction Site Stormwater Inspection Report (Appendix B) shall be used by the inspector during site visits. Construction site inspectors should abide by the following guidelines: 1. Inspections to monitor stormwater compliance should be performed at least once per month at each active construction site, with priority placed on sites that require coverage under the ADEQ 2020 CGP (i.e., that disturb one or more acres), and sites that are located in the watershed of any 303(d) water bodies (no 303(d) water bodies exist within Town of Oro Valley limits). 2. The inspection shall begin at a low point and work uphill, observing all discharge points and any off-site support activities. 3. Written and photographic records shall be maintained for each site visit. 4. During the inspection, the inspector should ask questions of the contractor. Understanding the selection, implementation, and maintenance of BMPs is an important goal of the inspection process, and requires site-specific input. 5. The inspector should not recommend or endorse solutions or products. The inspector may offer appropriate advice, but all decisions must be made by the contractor. 6. The inspector shall always wear personal protective equipment appropriate for the site. 7. The inspector shall abide by the contractor’s site-specific safety requirements. 8. The inspector has legal authority to enter the site. However, if denied permission to enter the site, the inspector should never force entry. Prior to planning a site visit, an inspector shall determine if the project is subject to requirements of the Arizona Department of Environmental Quality (ADEQ) 2020 Construction General Permit. Note for municipal inspectors: If a project disturbs one or more acres and is under construction, and there is no project ADEQ NOI on file, or the project is not listed in the ADEQ NOI database, the project is in violation of the 2020 CGP. Call the contractor to determine if the 60-03 SWPPP-Inspection-SOP Page 3 NOI process has been started. If not, notify the contractor verbally of this requirement and the violation. Work cannot proceed on the site until a Notice of Intent (NOI) for coverage under the 2020 Construction General Permit has been approved by ADEQ. Once it has been determined that the site is in compliance with the 2020 Construction General Permit, the site inspection process can continue. The Construction Site Inspection process shall include the following: 1. Plan the inspection before visiting the construction site; a. Obtain and review permits, site plans, previous inspection reports, and any other applicable information. b. Inform the contractor of the planned site visit. (depending on site compliance history, this may or may not be an option) c. This information and all records must be stores in the Cartegraph Operations Management System (OMS) 2. Meet with the contractor. a. Review the site SWPPP. • Compare BMPs shown on the approved SWPPP with those BMPs currently implemented on the construction site. b. Review the project’s approved NOI and confirm that the information shown continues to be accurate. (This is important because in some cases a new contractor begins operating under a new NOI at the same site. We want to document and track this type of occurrence). c. Get a general overview of the project from the contractor. d. Review site inspections done by the contractor. e. Review the status of any issues or necessary corrective actions noted in previous inspection reports. f. Discuss any complaints or incidents since the last meeting. 3. Inspect perimeter controls. a. Examine perimeter controls to determine if they are adequate, properly installed, and properly maintained. b. For each structural BMP, check structural integrity to determine if any portion of the BMP needs to be replaced or requires maintenance. 4. Inspect slopes or temporary stockpiles. a. Determine if sediment and erosion controls are effective. b. Look for slumps, rills, and tracking of stockpiled materials around the site. 5. Compare BMPs in the site plan with the construction site conditions. 60-03 SWPPP-Inspection-SOP Page 4 a. Determine whether BMPs are in place as specified in the site plan, and if BMPs have been adequately installed and maintained. b. Note any areas not shown on the approved SWPPP which may require the addition of BMPs. 6. Inspect site entrances/exits. a. Determine if there has been excessive tracking of sediment from the project site. c. Look for evidence of additional entrances and exits which are not shown on the approved SWPPP or site plans. 7. Inspect pollution prevention and good housekeeping practices. a. Inspect trash areas and material storage/staging areas to ensure that materials are properly maintained and that pollutant sources are not exposed to rainfall or runoff. b. Inspect vehicle/equipment fueling and maintenance areas for the presence of spill control measures and for evidence of leaks or spills. 8. Inspect discharge points and downstream, off-site areas. a. Walk down the street and/or in other directions off-site to determine if erosion and sedimentation control measures are effective in preventing off-site impacts. b. Inspect down-slope catch basins to determine if they are protected, and identify whether sediment buildup has occurred. 9. Meet with the contractor again prior to leaving. a. Discuss the effectiveness of current SWPPP BMPs and whether modifications are needed. b. Discuss possible violations or concerns noted during the site inspection, including discrepancies between approved site plans, the SWPPP, and/or currently implemented stormwater controls. c. Agree on a schedule for addressing all noted issues and schedule a follow-up inspection. 10. Provide a written or e -mailed copy of the inspection report to the contractor. 11. Follow up, as determined, and provide a copy of the subsequent re-inspection to the contractor. 60-03 SWPPP-Inspection-SOP Page 5 3.4 ENFORCEMENT PROCEDURES Once The Stormwater Utility Inspector has identified a violation on site the following actions may be taken: 1.Project Superintendent is alerted by Stormwater Utility Inspector and the violation is documented into Cartegraph. If superintendent is able to correct violation, post correction inspection is performed to verify. 2.Should superintendent not be able to rectify violation or fail to respond, the Stormwater Utility issues a Notice of Opportunity to Correct to both the owner and project contacts. If work is performed to correct, post correction inspection is performed to verify. 3.Failure to correct or respond to Notice of Opportunity to Correct, violation will be escalated to Stormwater Utility Manager and Town Engineer. Notification to Arizona Department of Environmental Quality will also be required by the Town. If work is performed to correct, post correction inspection is performed to verify. 3.5 TRAINING AND EDUCATION All Town of Oro Valley Stormwater Utility field staff will be certified as stormwater inspectors by the National Stormwater Center. Refresher training will happen at a minimum of every two years.

PURPOSE The purpose of the post-construction inspection procedure includes the following: 1. A reduction in the discharge of pollutants, to the maximum extent practicable, to the municipal separate storm sewer systems (MS4) permit area by completed construction projects. This is done through verification of the following: 1.1. Post construction site planning procedures are implemented and will reduce impacts to stormwater quality. 1.2. Structural and non-structural control measures are implemented and all temporary best management practices (BMPs) have been removed. 1.3. All post construction activities are operating in compliance with Town of Oro Valley code. 2. Post construction inspections are performed in accordance with the Arizona Department of Environmental Quality (ADEQ) small MS4 permit AZG2016-002 requirements found in section 6.4.5. 2. DISTRIBUTION 2.1. Public Works Stormwater Utility field personnel. 3. REVISIONS NA 4. PROCEDURE The ADEQ 2016 Small MS4 permit requires all completed construction sites be inspected and assessed for effective post-construction stormwater control. All finished construction sites shall be inspected no later than one year after cessation of construction activities. The procedures for data processing, field inspections, follow-up documentation and enforcement actions are outlined with the ultimate goal of bringing land management activities in compliance with Town of Oro Valley ordinances, and policies. 4.1. Update the Town of Oro Valley construction site inventory. For the purposes of inspection planning and data management, a Cartegraph SWPPP Asset of all construction projects within the Town of Oro Valley is utilized for compliance with MCM #5. The construction sites known to have filed for a Notice of Termination (NOT) with ADEQ or sites observed to have completed construction activities will be logged as Post Construction in the Page 2 of 5 60-05 Post Construction Inspection Procedure current site status box within Cartegraph. The date of the NOT or the date of the last inspection will serve as the beginning of the Town of Oro Valley post-construction inspection period. 4.2. Town of Oro Valley Post-Construction inspection procedure. Post-construction inspections document how well the applicable stabilization measures have been implemented. The inspection also includes verification that the temporary construction phase BMPs have been removed. The following criteria ensure Town of Oro Valley regulatory inspection compliance and that conveyance systems and pertinent structures are adequate to transport stormwater peak flow rates and minimize erosion at outlets. 4.2.1.

Section 1. Introduction 1.1 Background The Town of Oro Valley operates its storm drainage system under the authorization of the Arizona Pollution Discharge Elimination System (AZPDES) General Permit for Storm Water Discharges Associated with Small Municipal Separate Storm Sewer Systems (MS4s), hereafter referred to as the MS4 General Permit. The current MS4 General Permit, issued by the Arizona Department of Environmental Quality (ADEQ) is effective from September 30, 2021 through September 29, 2026. In accordance with Section 7.2 of the MS4 General Permit, The Town is required to sample stormwater discharges from the MS4 to protected surface waters at the outfalls identified by the Town in Part 7.2(4) of the permit. The Town is required to sample stormwater discharges from the MS4, as required in Appendix B, one (1) time within the first two (2) years of the effective date of the permit. This monitoring requirement is intended to provide discharge characterization data of stormwater discharges from the MS4 to State of Arizona listed protected surface waters. 1.2 Purpose This plan was created to better understand/Estimate pollutant loading into state listed protected surface waters from Town of Oro Valley outfalls. This sampling and analysis plan will describe the Town’s wet weather stormwater characterization monitoring program for the 2021 through 2026 permit term. Section 2. Town of Oro Valley Receiving Water Bodies 2.1 Receiving Water Body Overview Two State of Arizona protected surface waters exist within the Town of Oro Valley, (none of which are impaired or outstanding surface waters). These surface waters are The Canada Del Oro Wash (State Highway 77 to Town Limits) and Big Wash (Town Limits to Canada Del Oro Wash). Town of Oro Valley municipal outfalls and associated receiving waterbodies are identified in Table 2-1. Figure 2-1. provides a map of the Town’s outfalls and associated receiving waterbodies. Table 2-1 Town of Oro Valley Municipal Outfall Locations. Monitored Outfall Number Receiving Water Status (Outstanding/Impaired) Outfall Name & Location MO-1 Canada Del Oro Wash No Oro Valley Marketplace at CDO (32.413681 -110.938654) MO-2 Canada Del Oro Wash No Villages Of La Canada at CDO (32.388240 -110.992683) MO-3 Canada Del Oro Wash No Steampump Ranch at Foothills Wash (32.404034 -110.953742) MO-4 Canada Del Oro Wash No Canyon Shadows at CDO (32.382664 -111.003724) MO-5 Canada Del Oro Wash No Rooney Wash Shopping Center at Rooney Wash (32.396773 -110.965366) MO-6 Canada Del Oro Wash No CDO at Riverfront Park (32.396978 -110.974760) MO-7 Canada Del Oro Wash No CDO at SADDLE VALLEY II (1-54) (32.384537 -110.991572) MO-8 Canada Del Oro Wash No CDO at Rooney Wash (32.396880 -110.965965) MO-9 Canada Del Oro Wash No CDO at RIVERS EDGE (103-120) (32.399202 -110.967858) Of the 23 identified outfalls within the Town of Oro Valley all sampling sites (9 municipal outfalls) are located along the Canada Del Oro Wash. Of the remaining 14 outfalls, 11 are located on private property with 9 along Big Wash near the Oro Valley Marketplace and 2 along the CDO. 3 other outfalls exist along the CDO and fall under Pima County jurisdiction. According to the 2021 MS4 General Permit “the identified outfalls for this one-time characterization monitoring must be reported in a discharge monitoring report (DMR), including the identification of the land use for the area served by the outfall from the following three uses: residential, commercial, industrial. The permittee’s selected outfalls must be representative MS4 dischargers and discharge to a protected surface water”. The Town of Oro Valley has no industrial sites discharging into or near a State listed protected surface water. The monitoring locations will be representative of the general land uses within the Town and will be a mixture of 5 residential and 4 commercial outfalls along the Canada Del Oro watercourse. For a map of the 9 outfalls being monitored through this plan, see figure 2-1 below.

Stormwater Characterization Monitoring Constituents and Personnel 3.1 Analytical Constituents Stormwater runoff from urbanized areas may contain high concentrations of toxic metals, hydrocarbons, pesticides, bacteria, nutrients and sediments. It is essential that sample analyses meet specific criteria. These analytic objectives for the Town of Oro Valley samples are shown in Appendix A of this document, which outlines the sampling parameters, units of measure for each parameter, the monitoring frequency, and the monitoring type to be used for this plan. 3.2 The Sampling Team The Sampling Team refers to all Stormwater Utility personnel who may be involved in the characterization monitoring program. See Table 3-1 for a list of Town of Oro Valley personnel involved in this sampling and analysis plan.

Manual grab samples have been chosen as the sampling method for this program. This technique has been found to be most suitable for every constituent on the list of pollutants to be monitored in the AZG2021-002 MS4 General Permit. Manual grab samples will be taken at each site per the sampling protocols described in the NPDES Storm Water Sampling Guidance Document (U.S. Environmental Protection Agency, July 1992). According to this document, “a grab sample is a discrete, individual sample taken within a short period of time (usually less than 15 minutes). Analysis of grab samples characterizes the quality of a storm water discharge at the given time of the discharge.” Samples will be collected in clean, labeled bottles provided by the contracted laboratory. If necessary, an extension pole, rope or other apparatus will be used to aid the sampling crew in safe sample collection. Section 4.
