Construction Site Stormwater Runoff Control You must develop, implement, and enforce a program to reduce pollutants in any stormwater runoff to your small MS4 from construction activities within your jurisdiction that result in a land disturbance of greater than or equal to one acre or is less than one acre but is part of a common plan of development that will be one acre or greater. You must also select and implement a program of appropriate BMPs and measurable goals for this minimum control measure, at minimum: a. An ordinance or other regulatory mechanism to require erosion and sediment controls, as well as sanctions to ensure compliance, to the extent allowable under law. These ordinances or regulatory mechanisms must be in place by March 11, 2005; The City requires permits for all soil disturbing activities exceeding 10 cy in the shoreland district and 50 cy in area outside that district. These permits are reviewed by qualified construction site erosion control technicians for compliance with the City's SWPPP. Additionally all permits are inspected to ensure compliance. All development sites are required to have a SWPPP prior to construction. City Development contracts detail enforcement measures and requirements for all site developments. The City enforces all soil disturbance activities in accordance with the approved SWPPP. Currently the City has Grading and Filling and Storm Water Ordinances in place that deal with erosion control requirements not covered by permitting or development contracts. b. Requirements for construction site operators to implement appropriate erosion and sediment control best management practices; In place as discussed above. c. Requirements for construction site operators to control waste, such as discarded building materials, concrete truck washout, chemicals, litter, and sanitary waste at the construction site that may cause adverse impacts to water quality; Addressed in development contracts for larger projects and is handled on a case-by-case basis by Building Inspection Department for smaller sites. d. Procedures for site plan review which incorporate consideration of potential water quality impacts; The City review process requires a detailed water resource review (by a qualified professional engineer) that meets City of Prior Lake SWPPP and Prior Lake Spring Lake Watershed requirements. The City is currently updating our rules to meet Scott WMO requirements and future Non- degradation standards. e. Procedures for receipt and consideration of reports of non compliance or other 4 3/2/2005 information on construction related issues submitted by the public, and The City employs a full time technician who responds to all erosion and storm water non-compliance complaints on a same day basis. f. Procedures for site inspection and enforcement of control measures. The City has a variety of enforcement tools. For single residences that have not obtained permits a stop work order and restoration order can be issued. Any non-compliance issues that are not resolved immediately or in a timely manner are turned over to the City Attorney for legal enforcement. Failure to resolve issues. For projects requiring a building permit the City issues a stop work order followed by prosecution for failure to comply. For development or grading projects the City requires a Letter of Credit with sufficient funds to restore any disturbed areas. If a restoration order is ignored the City will draw on the LOC and fix the problem. The City also works closely with DNR Enforcement Officers when impacts to protected waters or wetlands are detected. 5.
