Preventative and Corrective Maintenance Action Plan Preventative and corrective maintenance shall be performed to maintain the function of the stormwater management measure, including, but not limited to, repairs or replacement to the structure; removal of sediment, debris, or trash; restoration of eroded areas; snow and ice removal; fence repair or replacement; restoration of vegetation; and repair or replacement of non-vegetated linings. Maintenance plans should include specific preventative and corrective maintenance tasks such as removal of sediment, trash, and debris; mowing, pruning, and restoration of vegetation; restoration of eroded areas; elimination of mosquito breeding habitats; control of aquatic vegetation; and repair or replacement of damaged or deteriorated components. Maintenance plans should include recommended corrective responses to various emergency conditions that may be encountered during and immediately after a storm event. It should be noted that if the stormwater management measure includes a Class I or II dam as defined in the NJDEP Dam Safety Standards at N.J.A.C. 7:20, an emergency action plan for the dam is also required. See N.J.A.C. 7:20-1.7(f) for more information. (Note: This project does not include a dam as part of the stormwater management system). The maintenance plan should address the maintenance of access points to the stormwater management measures in accordance with the following: - all components of the stormwater management measures must be readily accessible for inspection and maintenance; 2
