Do you have a regulatory mechanism(s) to address post-construction stormwater management activities? Yes No 1. If yes: a. Check which type of regulatory mechanism(s) your organization has (check all that apply): Ordinance Contract language Policy/Standards Permits Rules Other, explain: Comprehensive Water Resources Management Plan b. Provide either a direct link to the mechanism selected above or attach it as an electronic document to this form; or if your regulatory mechanism is either an Ordinance or a Rule, you may provide a citation: Citation: Code of Ordinances: Chapter 153, Storm Water Management Direct link: http://www.ci.saint-anthony.mn.us/vertical/sites/{5ED4AFB9-D450-4F68-BA29- 2600D3C2A620}/uploads/FULL_ORDINANCE12312013.pdf Check here if attaching an electronic copy of your regulatory mechanism, with the following file naming convention: MS4NameHere_PostCSWreg. B. Answer yes or no below to indicate whether you have a regulatory mechanism(s) in place that meets the following requirements as described in the Permit (Part III.D.5.a.): 1. Site plan review: Requirements that owners and/or operators of construction activity submit site plans with post-construction stormwater management BMPs to the permittee for review and approval, prior to start of construction activity. Yes No 2. Conditions for post construction stormwater management: Requires the use of any combination of BMPs, with highest preference given to Green Infrastructure techniques and practices (e.g., infiltration, evapotranspiration, reuse/harvesting, conservation design, urban forestry, green roofs, etc.), necessary to meet the following conditions on the site of a construction activity to the Maximum Extent Practicable (MEP): a. For new development projects – no net increase from pre-project conditions (on an annual average basis) of: 1) Stormwater discharge volume, unless precluded by the stormwater management limitations in the Permit (Part III.D.5.a(3)(a)). 2) Stormwater discharges of Total Suspended Solids (TSS). 3) Stormwater discharges of Total Phosphorus (TP). Yes No b. For redevelopment projects – a net reduction from pre-project conditions (on an annual average basis) of: 1) Stormwater discharge volume, unless precluded by the stormwater management limitations in the Permit (Part III.D.5.a(3)(a)). 2) Stormwater discharges of TSS. 3) Stormwater discharges of TP. Yes No 3. Stormwater management limitations and exceptions: a. Limitations 1) Prohibit the use of infiltration techniques to achieve the conditions for post-construction stormwater management in the Permit (Part III.D.5.a(2)) when the infiltration structural stormwater BMP will receive discharges from, or be constructed in areas: a) Where industrial facilities are not authorized to infiltrate industrial stormwater under an NPDES/SDS Industrial Stormwater Permit issued by the MPCA. Yes No
