La Cañada Drive • Oro Valley, Arizona 85737 fax: (520) 742-1022 • www.orovalleyaz.gov Town of Oro Valley Municipal Separate Storm Sewer System (MS4) Compliance Inspection – Response Narrative. The Town of Oro Valley (Town) has prepared the following documentation to address compliance issues as specified in the Arizona Department of Environmental Quality (ADEQ) “Municipal Separate Storm Sewer System (MS4) Compliance Inspection Report dated June 3, 2014. In a subsequent summery compliance letter dated July 18, 2014 nine compliance items were identified by ADEQ which are numbered below and presented in italics. The compliance items reflect requirements from “Permit Number AZG2002-002, Arizona Pollutant Discharge Elimination System General Permit for Discharge from Small Municipal Separate Storm Sewer Systems (MS4s) To Waters of The United States”, under which the Town was subject to at the time of the inspection. Specific permit parts are identified for each compliance item. Each italicized compliance item has then been broken down into applicable subcategories including definitions, office level enforcement, field level enforcement, standard operating procedures, recommended stormwater code changes and recommendations for inspections. Not all subcategories apply to every numbered compliance item. This document addresses in their entirety Town responses to the compliance items including the subcategories. Specific subcategories such as “Recommended Stormwater Code Changes” and “Standard Operating Procedures (SOPs)” are then formally presented in the required format for either Town Counsel review and approval or review and approval by Department management staff. Specific language in this document may vary slightly in format from that presented in the attached formal approval documentation. Also included is a summary spreadsheet of the compliance items and the general responses and documentation on Stormwater Pollution Prevention training material. Training material is further discussed in the compliance item number six (6). ADEQ Compliance Item 1: 1) Permit Part V.B.4.a – The Town has not enforced runoff controls for construction sites less than on acre that are part of a larger common plan of development that exceeds one acre. Provide documentation illustrating how the Town will enforce these controls. Definition - Larger common plan of development or sale: (common plan) is a contiguous area where multiple separate and distinct construction activities may be taking place at different times on different schedules under one plan. If the land is “parceled off” and/or sold, and construction occurs on plots that are less than one acre by separate, independent builders, this activity still would be subject to storm water permitting (NPDES/AZPDES) requirements if the smaller plots were included on the original site plan. Page 2 of 5 Enforcement – Common Plan Enforcement of the AZPDES/NPDES requirements for “common plan” site: Enforcement at the local level shall begin with inclusion of “common plan” requirement related verbiage in Article 15-24 “Stormwater” of the Town of Oro Valley, Town Code. Specific new “common plan” verbiage shall include the following: · Sec 15-24-14(C) Definitions – New definition for “Larger Common Plan of Development or Sale” (Recommended Inclusion) · Sec 15-24-14 (I) 4. - “New Development” – New subsection “a.” with verbiage for “common plan” requirements. (Recommended Inclusion) (See Attachment B: Construction General Permit (GCP) Compliance – Article 15-24 Stormwater Code Revision) Current Oro Valley verbiage addressing AZPDES: notification of spill/release, site inspection, discovered violations, and subsequent enforcement are found in Section 15-24-14 (O) through (CC). Office level “common plan” enforcement shall be achieved by inclusion of the “common plan” status and requirements in the CartêGraph tracking database and review checklists. Field enforcement shall be achieved by inclusion of the requirements in inspection checklists. Standard Operating Procedure (SOP) for determining “common plan” status:” (See Attachment A: SOP) ADEQ Compliance Item 2: 2) Permit part V.B.4.a. – The Town shall require some level of best management practices (BMPs) for all types of grading activities permitted within the Town, including those less than one acre. Provide documentation illustrating how the Town will develop and enforce grading BMPs. This ADEQ comment item refers to all construction activities including activities that are less than one acre and are NOT part of a “Common Plan”. Owners and/or operators of these sites are required to deploy BMP measures approved by the Town on a “case-by-case” basis. Specific information regarding: SWPPP measures, specific types of BMPs, and proper installation and functionality of BMPs may be found in the list of references identified below. References may include, but are not limited to the following documents: · Current CGP Permit – “Permit No. AZG2008-001” · ADEQ AZPDES Fact Sheet CGP for Stormwater Discharges Associated with Construction Activities – June 3, 2013 · ADOT Erosion and Pollution Control Manual – For Highway Design and Construction – ADOT – Intermodal Transportation Division – The W LB Group, Inc. June 1995 · Maricopa County – Stormwater Pollution Control Methods – Best Management Practices. · Town Code - Stormwater - Article 15-24 · Town Code - Floodplain and Erosion Hazard Management - Chapter 17 Page 3 of 5 Town of Oro Valley staff shall use the documents identified above in conjunction with known site topography, drainage conditions etcJ to identify specific stormwater management needs for the site in question. For subject sites less than or equal to one (1) acre in aerial extent, BMP measures will be evaluated on a site-by-site basis. Enforcement of stormwater runoff controls for any and all construction activities is identified in 15-24-14 I. 4 and 5. ADEQ Compliance Item 3: 3) Permit part V.B.4. – The Town shall require stormwater pollution prevention plans (SWPPPs) for construction sites that are less than one acre but are part of a larger plan of development that is greater than one acre. Provide documentation illustrating how the Town will require SWPPPs for these construction sites. TOV shall require complete SWPPP submittal for sites that are under one acre and that are a part of a larger “common plan” of development. The “common plan” status of a parcel/site will be tracked and accounted for on TOV CartêGraph permit tracking software and inspection checklist. Sites that are determined to be part of a “common plan” shall require submittal of a SWPPP and a NOI filed with ADEQ. Legal authorization for SWPPP submittal requirements for sites that fall under AZPDES requirements is identified in Section 15-24-14 I. (1-4) of the Town of Oro Valley stormwater management code. ADEQ Compliance Item 4: 4) Permit Part V.B.4.d. – The Town should escalate inspection deficiencies to enforcement if site operators are not responsive to normal communications. Provide documentation illustrating how the Town will conduct enforcement escalation procedures for nonresponsive site operators. Appropriate Town Code verbiage is currently in place to legally facilitate enforcement of non- compliant site operators.
