BMP #1: Enact, implement and enforce an ordinance or SOP to require post-construction stormwater management from new development and redevelopment projects, including sanctions for non-compliance.

Do you have an ordinance (municipal) or SOP or other mechanism (non-municipal) that requires implementation and maintenance of post-construction stormwater management (PCSM) BMPs? ☒ Yes ☐ No If Yes, indicate the date of the ordinance or SOP: 10/2011

If Yes to #1, is the ordinance or SOP consistent with DEP's 2022 Model Stormwater Management Ordinance (3800-PM-BCW0100j)? ☒ Yes ☐ No

If Yes to #2 and the ordinance or SOP has not been submitted previously, attach a copy of the ordinance or SOP.

BMP #2: Develop and implement measures to encourage and expand the use of Low Impact Development (LID) in new development and redevelopment. Measures should also be included to encourage retrofitting LID into existing development. Enact ordinances consistent with LID practices and repeal sections of ordinances that conflict with LID practices.

If Yes to #2 and the ordinance or SOP has not been submitted previously, attach a copy of the ordinance or SOP.

BMP #3: Ensure adequate O&M of all post-construction stormwater management BMPs that have been installed at development or redevelopment projects that disturb greater than or equal to one acre, including projects less than one acre that are part of a larger common plan of development or sale.

Do you have an inventory of all PCSM BMPs that were installed to meet requirements in NPDES Permits for Stormwater Discharges Associated with Construction Activities approved since March 10, 2003? ☐ Yes ☒ No

If Yes to #1, complete Table 1 on the next page.

Has proper O&M occurred during the reporting period for all PCSM BMPs? ☐ Yes ☒ No

If No to #2, explain what action(s) the permittee has taken or plans to take to ensure proper O&M.

Millcreek Township is in the process of compiling an inventory of all PCSM BMPs installed since March 10, 2003. Currently, and in the past, developers have been required to sign an O&M agreement, but at this point an ongoing inspection program has not been established. The BMPs are inspected at the time of construction, but further inspection and maintenance is the responsibility of the property owner. In the past, the township has been notified of maintenance issues predominantly on a complaint basis. Moving forward, once the PCSM BMP list has been made, an inspection plan will be developed.

If you are relying on PA's statewide program for stormwater associated with construction activities, you may skip to MCM #6, otherwise complete all questions for BMPs #4 - #6 in this section.

BMP #4: Require the implementation of a combination of structural and/or non-structural BMPs that are appropriate to the local community, that minimize water quality impacts, and that are designed to maintain pre-development runoff conditions.
