A. 
The purpose of this "Post-Construction Stormwater Management Ordinance" (the "Ordinance") is to provide for the health, safety, and general welfare of the citizens of the City of Westbrook through monitoring and enforcement of compliance with post-construction stormwater management plans in order to comply with minimum control measures requirements of the federal Clean Water Act,[1] of federal regulations and of Maine's Small Municipal Separate Storm Sewer Systems General Permit.

Editor's Note: See 33 U.S.C. § 1251 et seq.
B. 
This article establishes methods for post-construction stormwater management in order to comply with minimum control measures requirements of the federal Clean Water Act, of federal regulations and of Maine's Small Municipal Separate Storm Sewer Systems General Permit.
This article seeks to ensure that post-construction stormwater management plans are followed and stormwater management facilities are properly maintained and pose no threat to public safety.
The provisions of this article are hereby declared to be severable. If any provision, clause, sentence, or paragraph of this article or the application thereof to any person, establishment, or circumstances shall be held invalid, such invalidity shall not affect the other provisions, clauses, sentences, or paragraphs or application of this article.
The City of Westbrook enacts this "Post-Construction Stormwater Management Control Ordinance" (the "Ordinance") pursuant to 30-A M.R.S.A. § 3001 (municipal home rule ordinance authority), 38 M.R.S.A. § 413 (the "Wastewater Discharge Law"), 33 U.S.C. § 1251 et seq. (the "Clean Water Act"), and 40 CFR Part 122 [U.S. Environmental Protection Agency's regulations governing the National Pollutant Discharge Elimination System ("NPDES")]. The Maine Department of Environmental Protection, through its promulgation of the "General Permit for the Discharge of Stormwater from Small Municipal Separate Storm Sewer Systems," has listed the City of Westbrook as having a regulated small municipal separate storm sewer system ("small MS4"); under this general permit, listing as a regulated small MS4 necessitates enactment of this article as part of the municipality's stormwater management program in order to satisfy the minimum control measures required by Part IV D 5 ("Post-construction stormwater management in new development and redevelopment").
For the purposes of this article, the terms listed below are defined as follows:
APPLICANT

Whenever the enforcement authority believes that a person has violated this article or the post-construction stormwater management plan, the enforcement authority may order compliance with this article or with the post-construction stormwater management plan by written notice of violation to that person indicating the nature of the violation and ordering the action necessary to correct it, including, without limitation:
A. 
The abatement of violations, and the cessation of practices, or operations in violation of this article or of the post-construction stormwater management plan;
