If the entire water quality volume is not addressed on the site of the original construction activity, the remaining water quality volume must be addressed through off-site treatment and, at a minimum, ensure the requirements of permit items 20.11 through 20.14 are met. 101.H. Permit item 20.11: You must ensure off-site treatment project areas are selected in the following order of preference: a.Locations that yield benefits to the same receiving water that receives runoff from the original construction activity b.Locations within the same DNR catchment area as the original construction activity c.Locations in the next adjacent DNR catchment area up-stream d.Locations anywhere within your jurisdiction 101.I. Permit item 20.12: Off-site treatment projects must involve the creation of new structural stormwater BMPs or the retrofit of existing structural stormwater BMPs, or the use of a properly designed regional structural stormwater BMP. Routine maintenance of structural stormwater BMPs already required by this permit cannot be used to meet this requirement. 101.J. Permit item 20.13: Off-site treatment projects must be completed no later than 24 months after the start of the original construction activity. If you determine that more time is needed to complete the treatment project, you must provide the reason(s) and schedule(s) for completing the project in the annual report. 101.K. Permit item 20.14: If you receive payment from the owner of a construction activity for off-site treatment, you must apply any such payment received to a public stormwater project, and all projects must comply with permit items 20.11 through 20.13. 101.L.

If structural stormwater BMPs change, causingdecreased effectiveness, new, repaired, or improved structural stormwater BMPs must be implemented toprovide equivalent treatment to the original BMP. *102. Permit item 20.16: Do you maintain a written or mapped inventory of structural stormwater BMPs that you do not own or operate that meet all of the following criteria? (Note: All or some of this item is a new permit requirement. Compliance with new requirements is required within 12 months after receiving permit coverage.) a.The structural stormwater BMP includes an executed legal mechanism(s) between you and owners responsible for the long-term maintenance, as required in item 20.15; and b.The structural stormwater BMP was implemented on or after August 1, 2013. Yes No *103. Permit item 20.17: Do you to have written procedures for site plan reviews to ensure compliance with requirements of your regulatory mechanism(s)? Yes No *104.
