City of Newark, Ohio FINAL REPORT Stormwater Management Program for the City of Newark, Ohio April 2009 Report Prepared For: City of Newark 40 West Main Street Newark, Ohio 43055 0821249 INDEPENDENT ENVIRONMENTAL ENGINEERS, SCIENTISTS AND CONSULTANTS Introduction The City of Newark (City) is located in central Licking County, Ohio, and encompasses approximately 19 square miles (12,300 acres) of land. The City is a component of the Licking County Urban Area (UA), and, according to the 2000 Census, has a population of approximately 46,279 people. While the majority of the property inside the corporation limits of Newark is identified as part of the UA, some City property lies outside of the UA boundary. To provide continuity, the City considered the entire land area within the city limits when initially developing the stormwater management program (SWMP). The City lies within the greater Muskingum River watershed and the Licking River sub-basin (HUC 05040006). Primary receiving waters include Raccoon Creek, North Fork of the Licking River, South Fork of the Licking River, Licking River and Log Pond Run. Ohio Environmental Protection Agency (Ohio EPA) performed field work in 1993 in the Licking River basin and summarized associated findings in a report entitled Biological and Water Quality Study of the Licking River and Selected Tributaries. Results indicated that the Licking River fully attained warmwater habitat (WWH) aquatic life use except immediately downstream of Dillon Lake, which lies south of the City of Newark in Muskingum County. In the summer of 2008, Ohio EPA began a new study of the Licking River watershed as a first step toward creating a Total Maximum Daily Load (TMDL). The TMDL is mandated by the Clean Water Act to identify waterways failing to meet state water quality standards as well as the source and type of pollutants causing the failure. According to Ohio EPA, the Licking River TMDL is scheduled for completion in 2009. Regulatory Overview In compliance with the provisions of the Federal Water Pollution Control Act, as amended (33 U.S.C. 1251 et. seq.), and the Ohio Water Pollution Control Act (Ohio Revised Code Chapter 6111), the Ohio EPA required designated small Municipal Separate Storm Sewer Systems (MS4s) to obtain coverage under National Pollutant Discharge Elimination System (NPDES) General Permit No. OHQ000001 issued on December 27, 2002. Subsequently, a renewal permit, NPDES General Permit No. OHQ000002 (General Permit) was issued on January 30, 2009 (Appendix A). The Ohio EPA defines an MS4 as a conveyance system or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, man-made channels, or storm drains) that are owned or operated by a public body and designed or used for collecting or conveying solely stormwater. Small MS4s refer to systems serving populations of less than 100,000 people in urbanized areas and MS4s that have or may have the potential to negatively impact surface water quality as a result of their discharges. Coverage under the General Permit is intended to reduce the discharge of pollutants from small MS4s which in turn degrade receiving water quality. Potential negative results associated with degraded receiving water quality include, but are not limited to, contamination of drinking water supplies and recreational waterways, destruction of aquatic habitat, and the reduction of the aesthetic value of local receiving waters. Granting of general permit coverage was conditioned upon payment of applicable fees, submittal of a Notice of Intent (NOI), as well as development and implementation of a SWMP. The SWMP was required to address six minimum control measures (MCMs) over the five year permit period through the implementation of associated best management practices (BMPs). The City developed and submitted their SWMP to the Ohio EPA in March 2003 in Source: www.cityofmarion.org accordance with the regulations in the first general permit. The first general permit cycle expired on December 26, 2007 and the Ohio EPA recently issued a renewed General Permit as described previously. This updated SWMP and associated BMPs address the requirements of this new permit. City of Newark’s Stormwater Management Program The City developed their existing SWMP in March 2003 with updates made in October 2004. The City’s SWMP was designed to reduce the discharge of pollutants from their MS4 to the maximum extent practicable. In turn, measures taken to implement the SWMP serve to protect receiving water quality and satisfy the General Permit requirements. The City’s SWMP includes management practices that are structured around six MCMs, as set forth in the General Permit: 1. Public Education and Outreach on Stormwater Impacts 2. Public Involvement/Participation 3. Illicit Discharge Detection and Elimination 4. Construction Site Stormwater Runoff Control 5. Post-Construction Stormwater Management in New Development and Redevelopment 6. Pollution Prevention/Good Housekeeping for Municipal Operations Since submittal of the original SWMP, organizational changes have occurred within the City. An analysis of problems, needs, missions, goals, as well as financing and management options led to the formation of a stormwater utility in December 2005. This utility established a stormwater rate structure that provides funding for the operation, maintenance, and improvement of the stormwater system within the City limits. A copy of the stormwater utility ordinance (Ordinance No. 05-55) is included in Appendix B. Additionally, a stormwater coordinator was hired and a portion of stormwater utility revenues were dedicated to implementing the SWMP. The stormwater utility works closely with the Engineering, Water and Wastewater, and Streets Departments as well as City Administrators, leveraging existing staff and programs to reduce stormwater pollution. The City has also invested in the GBA Master Series (gbaMS) asset management software and the ASIST© Stormwater Database Management Systems software. The gbaMS software is used to inventory and track City-owned stormwater assets as well as to document City inspections and work orders associated with that infrastructure. ASIST© efficiently tracks and reports stormwater permit compliance activities that are more programmatic such as public education and outreach, construction site runoff control and pollution prevention and good housekeeping. This updated SWMP considers the program developments discussed above and provides a roadmap for continuing to reduce stormwater pollution over the next five year permit cycle. Information specific to each MCM has been updated including discussion of the following: Target pollutants; BMPs; Entities with legal authority to implement each BMP; Measurable goals for each BMP Persons responsible for the implementation of each BMP; and, Rationale for the BMPs and measurable goal selection process The City recognizes that certain pollutants have a greater potential for impact on area receiving water quality. Target pollutants identified by the City include sediment and yard/pet waste. Updated BMPs in the SWMP are structured in order to address potential sources of these pollutants. Other pollutants that are peripherally addressed in the SWMP revision include household hazardous chemicals as well as oil and grease. The updated SWMP will provide the City with clearly delineated measurable goals and a means to evaluate the overall success of their program. Additionally, a clear designation of parties responsible for the implementation of each component of the SWMP will allow for better internal communication and efficient program management. The City has the legal authority to implement all BMPs within this SWMP, except for BMP 3.03 which will be a coordinated effort between the City and the Licking County Health Department. The details of this BMP are discussed further in Section 3. The overarching authority for the City’s SWMP is the City Engineer. However, daily management of SWMP implementation activities is delegated to the City’s Stormwater Coordinator. As discussed previously, SWMP implementation activities are divided among appropriate City Departments, including the Streets, Water and Wastewater, and Engineering Departments. Figure 1 provides an organization chart which identifies the person or persons responsible for implementing or coordinating each BMP referenced in this SWMP. v Brian Morehead John Trujillo Phone: 740.670.7720 Phone: 740.670.7762 City Engineer Stormwater Coordinator Roger Loomis Dave Reed Brian Morehead Joseph Ebel Phone: 740.670.7762 Phone: 740.670.7728 Phone: 740.670.7720 Phone: 740.349.6535 Water and Streets Engineering Licking County Wastewater BMPs: BMPs: Health Dept BMPs: 2.08 6.02 4.04 5.04 BMPs: 3.02 3.09 6.04 6.06 5.06 5.07 3.03 4.04 6.02 6.07 6.08 6.02 6.09 Ed Clark Phone: 740.670.7722 Roger Stollard Lindsey Grimm Jeff Hostchkiss Phone: 740.670.7710 Phone: 740.670.5330 Stormwater Phone: 740.670.7778 Inspector Parks and Safety Licking SWCD BMPs: 3.02 3.03 Cemetery BMPs: BMPs: 3.04 3.05 BMPs: 6.02 1.04 1.09 3.09 3.10 1.12 6.05 2.04 4.05 4.06 6.02 4.07 4.08 6.04 4.09 5.03 5.04 5.08 Note: The overarching authority for the SWMP is the City Engineer.
