Additional stormwater treatment controls for Hart Brook Watershed ---PAGE BREAK--- SECTION 1 INTRODUCTION Section 1.1 Overview of Regulatory Program The Environmental Protection Agency (EPA) amended the Clean Water Act in 1987 to require a national program to address stormwater impacts on water quality. This program, the National Pollutant Discharge Elimination System (NPDES) requires industrial, municipal and other facilities that discharge directly to surface waters to obtain a permit to do so. The program was implemented in two phases: Phase I, governing approximately 900 of the nation’s largest cities, was initiated in 1990 and Phase II in 1999. Phase II regulates municipal separate storm sewer systems (MS4s) located in urbanized areas (UA) with populations of fewer than 100,000 people. The State of Maine has authority to administer this program, referred to as the Maine Pollutant Discharge Elimination System (MEPDES) Phase II permit. The General Permits for Discharge of Stormwater from Small Municipal Separate Storm Sewer Systems and State or Federally Owned Separate Storm Sewer Systems (included as Appendix B and C respectively and heretofore referenced as the "General Permit") were issued by the Maine Department of Environmental Protection (DEP) on July 1, 2008. The General Permit authorizes the direct discharge of stormwater from or associated with a regulated small municipal or State or federally owned separate storm sewer system (“MS4”) to a MS4 or waters of the State other than groundwater. Discharges must meet the requirements of the General Permit and applicable provisions of Maine's waste discharge and water classification statutes and rules. Compliance with the General Permit authorizes a person to discharge stormwater, pursuant to 38 M.R.S.A. § 413. The General Permit authorizes direct discharges in those parts of Maine for which the Department has received delegated authority under the Federal NPDES program. Several key requirements of the General Permit are described below. Section 1.1.1 Notice of Intent and Stormwater Management Plan The Cities of Lewiston, Auburn and Sabattus (LAS) qualify as MS4 communities, therefore, are required to submit a Notice of Intent (NOI) to operate under the MEPDES Phase II permit. The first five year permit cycle was 2003- 2008. The cities submitted NOIs, which included a listing of Best Management Practices (BMPs) that they proposed to implement over the five year permit cycle to ensure compliance with the MEPDES Phase II permit. The permit required annual reporting as to status of maintaining permit compliance. The final report, submitted September 26, 2008, also included a summary of BMPs initiated during the 03-08 permit cycle which were not completed, a justification of why they were not completed and a plan for addressing these deficiencies in the next permit cycle. The second five year permit cycle will be 2008-2013 and required submittal of another NOI, and an updated and revised Stormwater Management Plan (SWMP) to ensure compliance with the new permit. This NOI was submitted on July 1, 2008. The cities of Lewiston, Auburn and Sabattus have submitted individual NOIs referencing a single joint SWMP which is provided with this submittal. ---PAGE BREAK--- The cities of Lewiston, Auburn and Sabattus have jointly developed this SWMP to ensure compliance with the 2008-2013 MEPDES Phase II General Permit for the Discharge of Stormwater from Small Municipal Separate Sewer Systems, which became effective on July 1, 2008, with the submission of the individual NOIs. The SWMP includes all BMPs proposed to be implemented over the next five year permit cycle. Many of the BMPs are carry-overs from the previous permit which will be continued and some are new that are proposed to be initiated during the 08-13 permit cycle. Section 1.1.2 Minimum Control Measures Per the General Permit, the BMPs have been developed to meet the Minimum Control Measure (MCM) listed below. MCM Public Education and Outreach on Stormwater Impacts MCM Public Involvement and Participation MCM Illicit Discharge Detection and Elimination MCM Construction Site Stormwater Runoff Control MCM Post-construction Stormwater Management in New Development and Redevelopment MCM Pollution Prevention/Good Housekeeping for Municipal Operations For all BMPs, the plan includes the measurable goals, the reporting criteria and the responsible party (ies). Section 1.1.3 Evaluation and Assessment As specified in Part IV of the General Permit, the regulated MS4 shall evaluate program compliance, the appropriateness of identified best management practices, and progress towards achieving identified measurable goals. The Plan must address the six Minimum Control Measures as required in the permit. The Plan must, at a minimum, include the measures indicated as required within the UA of the municipality. The permittee may also include in the Plan those measures indicated as suggested and any other measures the permittee deems appropriate. Some municipalities may choose to implement required measures or portions there of throughout the entire municipality, however the General Permit only requires implementation of the minimum control measures within the UA to the extent the measures will have an impact on the MS4, and for municipal facilities, operations and activities within the UA, that discharge to waters of the State other than groundwater. ---PAGE BREAK--- Section 1.1.4 Annual Reporting and Record Keeping The regulated MS4 shall keep records required by the permit for at least three years following its expiration or longer if requested by the Commissioner. The regulated MS4 shall make records, including its Stormwater Program Management Plan, available to the public at reasonable times during regular business hours. By September 1, 2009, and annually thereafter by September 1, the regulated MS4 shall submit a report for the Department’s review and approval to: Municipal/Industrial Stormwater Coordinator Department of Environmental Protection 17 State House Station Augusta, Maine 04333-0017 The report must include the following. a. The status of compliance with permit conditions based on the permittee's Plan, an assessment of the appropriateness of identified best management practices, progress towards achieving identified measurable goals for each of the Minimum Control Measures, and progress toward achieving the goal of reducing the discharge of pollutants to the maximum extent practicable (MEP). b. Results of information collected and analyzed, including monitoring data, if any, during the reporting period. c. A summary of the stormwater activities the permittee intends to undertake pursuant to its Plan during the next reporting cycle. d. A change in any identified BMPs or measurable goals that apply to the Plan. e. A summary describing the activities, progress, and accomplishments for each of the minimum control measures #1 through #6 (including such items as the status of education and out reach efforts, public involvement activities, stormwater mapping efforts, dry weather inspections, detected illicit discharges, detected illicit connections, illicit discharges that were eliminated, construction site inspections, number and nature of enforcement actions, post construction BMP status and inspections, and the status of the permittee’s good housekeeping/pollution prevention program. Changes to the report based on the Department’s review comment(s) must be submitted to the Department within 30 days of the receipt of the comment(s). If possible, the permittee shall provide an estimate of annual expenditures for permit compliance for the reporting period and projected budget for the following year. Section 1.1.5 Impaired Waters and Total Maximum Daily Load (TMDL) If the waterbody to which a discharge drains is impaired and has an EPA approved TMDL, then the discharge must be consistent with the TMDL waste load allocation and ---PAGE BREAK--- any implementation plan. If a TMDL is approved or modified by EPA subsequent to the effective date of this General Permit, the Department shall notify the permittee and may: 1. Require the permittee to review its Plan for consistency with the TMDL, and propose any necessary modification to the Plan to be submitted to the Department within six months of the receipt of notification concerning the TMDL; 2. Issue a watershed-specific General Permit for the area draining to the impaired waterbody. The watershed-specific MS4 General Permit may reference parts of this General Permit; or 3. Require an individual permit. Section 1.2 Basis of Plan Development This Stormwater Program Management Plan was developed in accordance with the requirements of the General Permit for the Discharge of Stormwater from Small Municipal Separate Storm Sewer Systems, which was issued by the Maine Department of Environmental Protection (DEP) on July 1, 2008. The General Permit requires the implementation of the six (MCMs) only within the urbanized area (as defined by the U.S. Bureau of Census) of the regulated small MS4. The Cities of Lewiston and Auburn plan to apply the Plan to the entire municipal area, not just the urbanized area. The Town of Sabattus is in the process of determining whether to apply the Plan to the entire municipal area or restrict the application to only the urbanized area. Section 1.3 Responsibility for MS4 Compliance Each individual MS4 is independently responsible for meeting the terms and conditions of the General Permit. Each regulated MS4 in the Lewiston/Auburn/Sabattus Working Group (LASSWG) acknowledges that they must meet the requirements of the General Permit. This plan provides a regional methodology for accomplishing what each individual MS4 is responsible to do independently. No MS4 will be responsible for the non-compliance of another MS4. Working together the three municipalities will employ methods by which they may be able to reduce the costs and improve the effectiveness of compliance activities. ---PAGE BREAK--- SECTION 2 REGULATED MS4 INFORMATION Section 2.1 LASSWG Background The LASSWG was formed in 2008 to collaborate on the implementation of Maine’s MS4 Program for the second five year permit cycle, 2008-2013.
