Existing Water Quality Programs 3.1 Local Programs 3.1(a) Stormwater Management Ordinance The City of Monroe administers a Stormwater Management Ordinance to control stormwater pollutants as well as increased stormwater volume and velocity from new development and redevelopment sites so that water quality is protected and downstream flooding is reduced. The ordinance requires a stormwater control measure (SCM) for all development and redevelopment within the corporate limits or in the extraterritorial jurisdictions within the City of Monroe. Zoning requirements also require buffers along designated streams to help retain stream water quality along developing sites. 3.1(b) Erosion and Sedimentation Control Program The City of Monroe was delegated the responsibility of administering its own Erosion and Sedimentation Control Program in June 2002. The policy parallels the State of North Carolina requirements with some modifications which include a maximum of 12,000 s.f. of disturbed area without a grading permit. The City of Monroe enforces the program through an inspection and plan review process, as well as issuing fines and citations for violations. 3.1(c) Stormwater System Repair Program The City of Monroe offers private citizens the opportunity to correct or repair problem areas on private property due to public runoff. The City provides the necessary labor, equipment, and repair materials to qualifying projects. 3.2 State Programs 3.2(a) Stormwater Control Measure Stormwater Control Measure required for post -construction related sites follow the requirements of the N.C. Department of Environmental Quality. 3.2(b) Clean Water Act of 1977 The City of Monroe, in accordance with the Clean Water Act of 1977, requires Developers/Contractors to acquire Section 401 permits for various activities related to stream and wetland water quality. 7 ,m 4.

Stormv,,ater Management Program Plan 7.1 Public Education and Outreach on Storm Water Impacts 7.1.1 BMP Summary Table (See Appendix A for Further Information) 1.) Distribute brochures to groups and citizens at various events including neighborhood meetings and public events 2.) Present storm water information to students and teachers 3.) Maintain City website with stormwater information 4.) Continue to work with Regional Stormwater Partnership of the Carolinas to promote good stormwater practices at both the local and regional levels. 7.1.2 Target Audience: The target audience for this measure will be the general public ranging from homeowners to students to business owners. The Spanish-speaking and other non-English speaking communities will be included as well. 13 7.1.3 Target Pollutant Sources: 1.) Oils and Greases: Petroleum products can suffocate living organisms and cause harmful secondary chemical compounds, as well as clog sewer lines and harm equipment. 2.) Trash: Trash can clog sewer lines and cause hazardous water blockages. 3.) Sediment: Sediment can clog storm pipes and suffocate wildlife in the creeks and streams by invading the gills of fish and destroying habitat areas. 4.) Herbicides/Pesticides: Specific chemicals are toxic to different species of wildlife and plant life. Runoff into the storm system can carry these chemicals into the streams and creeks. 5.) Nutrients: Excess nutrient can cause algae and bacteria blooms in our lakes and streams. Algae will consume oxygen, increase turbidity in the water body and eventually die along with the fish and other aquatic life that need oxygen to live. In addition, excess nutrient can lead to taste and odor in the drinking water. 7.1.4 Outreach Program: Information concerning public education will be distributed at neighborhood meetings, classroom presentations, public events, by word-of-mouth, fliers, brochures and the City's website. The number of citizens reached by these methods is expected to be in the order of 1,000 people at neighborhood meetings and public events and 15,000 people with utility billing. 7.1.5 Evaluation: A count of the number of people that attend educational events of the effectiveness of the program. In addition, positive response from the general public includes citizens. 7.2 Public Involvement and Participation 7.2.1 BMP Summary Table (See Appendix A for Further Information) 1.) Conduct a Public Meeting on the Stormwater Management Plan 2.) Maintain and promote the stormwater Hotline 3.) Coordinate volunteer community involvement programs a. Storm Drain Marking b.

Civic groups will be encouraged to participate, as well as any other concerned citizens group. 7.2.3 Participation Program: A public meeting will be held by the Public Enterprise Committee to allow the general public to comment on the Stormwater Management Plan and the associated program. Civic and neighborhood group members will be encouraged to volunteer to participate. They will also be encouraged to get involved in the various volunteer programs. 7.2.4 Evaluation: Attendance and involvement in various stormwater events and volunteer programs will gauge the effectiveness of the measure. 7.3 Illicit Discharge Detection and Elimination 7.3.1 BMP Summary Table (See Appendix A for Further Information) 1.) Train and coordinate with other departments to report illicit connections. 2.) Continue to distribute brochures to the public educating them on illicit connections. 3.) Continue to provide for public involvement to report illicit connections. 4.) Develop and implement a program to conduct dry weather flow Illicit Discharge detection program. 7.3.2 Storm Sewer System Map: The City of Monroe currently has maps depicting the location of storm sewer system pipes and appurtenances in a GIS format. The maps also indicate creek and stream names. The maps were developed utilizing a GPS surveying system. As new systems are added or existing systems are amended, the map will be updated utilizing the GPS surveying system. 7.3.3 Regulatory Mechanism and Annual Review: The City of Monroe will continue to use the existing Section 159-701 Illicit Discharges and Connections of the Stormwater Management ordinance that addresses cross connections and discharges into the stormwater system. 7.3.4 Enforcement: The Section 159-701 Illicit Discharges and Connections of the Stormwater Management ordinance makes it a violation to cause or allow the discharge, emission, disposal, pouring, 15 pumping, or connect directly or indirectly to any stormwater conveyance, the waters of the State, or upon the land in any manner for purposes of discharging anything other than stormwater runoff into the system. The language in the ordinance contains, as a minimum, that a notification will be issued to the owner outlining the procedures for remediation and consequences for non-compliance. 7.3.5 Detection and Elimination: The City will continue to use existing City personnel, citizens and civic groups to detect illegal discharges and connections to stormwater conveyance systems through the Illicit Discharges and Connections program. Inspections and evaluations will be conducted during dry weather periods when illegal flows will be most obvious, or in response to reports received from city personnel or the general public. 7.3.5.1 Procedures for Locating Priority Areas: Those areas where parcels are not yet connected to public sewer and depend upon septic systems will be examined on maps. Inspection of older existing sanitary sewer lines by the Water Resources Department will help identify those areas where a potential for cross contamination could occur. The public at large will be provided the ability to report illicit connections. Employees will be trained in the use of detection methods. 7.3.5.2 Procedures for Tracing the Source of the Illicit Discharge: The City will use various methods to trace the source of the illicit discharge including but not limited to visual inspection, field screening, and TV the stormwater system as required. 7.3.5.3 Procedures for Removing the Source of the Illicit Discharge: The Illicit Discharges and Connections ordinance gives the City the authority to remove illegal connections and discharges. City employees are given the authority to enter upon private property for purposes of inspection and empowered to issue fines and Notice of Violations. 7.3.5.4 Procedures for Evaluation of Illicit Connection and Discharge Component: An annual review of the illicit connection detection program by City staff will gauge its effectiveness. The effectiveness will be measured by comparing the number and type of illicit connection identified and corrected during the reporting period. 16 7.3.6 Non Stormwater Discharges: Activity Allowed Not Allowed Water Line Sampling and Flushing X Landscape Irrigation X Diverted Stream Flows X Rising Ground Water X Uncontaminated Ground Water Infiltration * X Uncontaminated pumped ground water X Discharges from Potable Water Sources X Foundation Drains X Air Conditioning Condensation X Irrigation Water ** X Springs X Water from Crawlspace Pumps X Footing Drains X Lawn Watering X Individual Residential & Charity Car Washing X Flows from Riparian Habitats & Wetlands X Dechlorinated Swimming Pool Discharges X Street Wash Water X Flows from Emergency Fire Fighting X * As defined at 40 CFR §35.2005(20) ** Does not include reclaimed water as defined at 15A NCAC 2H .0200 7.3.7 Outreach: The public will be notified through the Public Education and Outreach Program about the hazards and potential effects of illegal connections. Internal training programs for City employees will be presented via the Pollution Prevention / Good Housekeeping Program. 7.3.8 Staff Training: Internal training programs for City employees will be presented via the Pollution Prevention / Good Housekeeping Program. As part of the internal training program, City employees will be informed on what City Department to call to report any illicit discharge or connection. 7.3.9 Evaluation: Measurement of the success of this program will be defined by the quality and quantity of the stormwater at the outfalls. A secondary measurement will be the number of illicit connections discovered and removed. 17 7.4 Construction Site Stormwater Runoff Control 7.4.1 BMP Summary Table: See Appendix A. 7.4.2 Regulatory Mechanism: Per the City of Monroe Ordinance, Title XV: Land Usage, Chapter 158: Erosion and Sedimentation Control, a grading permit is required for sites disturbing an area equal to 12,000 s.f. or more. The City of Monroe was delegated in June 2002 to review and enforce its own Sedimentation and Erosion Control Program. Copies are attached in Appendix B. 7.4.3 Plan Reviews: A grading plan for the site is prepared by a qualified professional and presented to the City of Monroe for review of erosion control measures. Site plans are also given to the Planning and Development Department for review of required natural buffers along streams, if applicable. Nonresidential sites disturbing 12,000 s.f. or more of area are required to obtain a grading permit. While residential sites disturbing one acre or more are required to obtain a grading permit. Single-family lot disturbing less than 1 acre must submit a Maintenance Agreement. Non-residential sites disturbing less than 12,000 sf. must submit a non-residential Installation and Maintenance Agreement. 7.4.4 Enforcement: The current Erosion and Sedimentation Control Ordinance provides for penalties to be assessed when site inspections reveal violations. If a site is in violation, a Notice of Violation is sent to the responsible party explaining the violation, which contains a remedy date by which corrections are to be made, and a warning that failure to comply can result in civil or criminal penalties. 7.4.5 Inspections: Construction sites are inspected as required. Those sites disturbing the greatest area and could pose a threat to adjoining streams and creeks are inspected first and more often. Commercial sites are inspected at least once per month or more frequently depending upon site deficiencies and rainfall events. Items are inspected as presented on the approved erosion control plan and, if needed, revision may be required to the approved plans and initiation of the revision for compliance. 7.4.6 Public Information: The Erosion and Sedimentation Control Ordinance was presented to City Council for approval and open to public discussion. As new amendments are made, the public will have the opportunity to comment. 18 7.4.7 Evaluation: The success of this program will be measured by the number of projects with sediment leaving the construction sites and the number of Notice of Violation (N.O. V.) issued and fines levied. 7.5 Post -Construction Site Runoff Controls 7.5.1 A copy of the City of Monroe Stormwater Management Ordinance is attached. See Appendix C. 7.5.2 Maintenance requirements of the SCM's are included in the Stormwater Management Ordinance. See Appendix C. 7.5.3 The City of Monroe owns and maintains its own wastewater collection system with non-sewered areas served by septic systems, as per City of Monroe Ordinance Title V, Chap. 52, § 52.010. See Appendix D. 7.5.4 No surface waters within the City of Monroe drain into SA waters. 7.5.5 No surface waters within the City of Monroe drain into TR waters. 7.5.6 No surface waters within the City of Monroe drain into Nutrient Sensitive waters. 7.5.7 BMP Summary Table: See Appendix A. 7.5.8 Non -Structural BMP's: 7.5.8.1 Zoning Ordinances for land development requires that proper vegetative buffers be placed or existing ones be maintained, along designated streams. Other measures include requirements for open space and landscaped areas in commercial and multi -family projects. 7.5.8.2 Interconnectivity of impervious surfaces is discouraged by requiring internal landscaped areas within project sites. 7.5.8.3 Conduct developer/contractor forums to address concerns with construction, inspection and long term maintenance of structural best management practices. 7.5.9 Structural SCM's: 7.5.9.1 Current water quality practices allow the use of wet detention ponds, in addition to those contained in the "Stormwater Design" manual by the N.C. Department of Environmental Quality (NC DEQ). 19 7.5.10 Regulatory Mechanism: In October 2007, the City of Monroe adopted a Stormwater Management ordinance that addresses post - construction runoff from new development and redevelopment.
