A. All development must establish stormwater management practices to control stormwater in compliance with § 8.28.050 of this chapter.
B. The city shall require that any person submitting a grading, building, or other improvement plan disclose if illicit discharge, stormwater, or permitted non-stormwater discharge of any type to the MS4 may occur as a result of, or in conjunction with the implementation of the plan. To the extent that the discharge would be an illicit discharge, if connected to the MS4, the plan shall include BMP measures to remove or prevent the illicit discharge during and after construction of the improvement or project. The BMP shall be subject to approval of the city.
C. Persons shall maintain the BMP during and after construction until such time as final stabilization of the site has been performed. This shall apply to persons initiating a project and to heirs and assigns. Changes to the BMP approved at the time of a project implementation shall be sent to the city in writing. The revised BMP shall be at least as effective in preventing pollution as the original BMP or as then currently required by the city. The city reserves the right to require changes in BMP as necessary to assure that discharges to the MS4 are of a quantity and quality that the city will not be in violation of the permits under which it is allowed to discharge stormwater. Sites requiring post construction (permanent) BMPs shall require an Operations and Maintenance Agreement be provided to the city identifying responsibility for operation and maintenance of the facility and for providing perpetual access to the city for inspection of the facility.
D. The city shall be granted access to all facilities and lands discharging any water or other material to the MS4.
E. Persons further developing parcels and/or lots that are part of a larger development, regardless of the time elapsed, shall utilize current BMP methods that are at least as effective as those identified in the stormwater pollution prevention plan for the larger development or necessary to comply with regulations, laws, and codes current at the time of further developing, whichever is more stringent. Appropriate permits required by the state shall be acquired by further developers.
F. Site-specific stormwater pollution prevention plans shall be developed for all construction projects 1 acre or greater in size and a Notice of Intent (NOI) shall be filed with ADEQ. The site-specific plan shall identify the minimum BMPs to be utilized upon further development of the project area, when the person submitting the plan will not develop the entire project though building occupancy or other full development intent. Smaller areas may develop a site-specific plan.
G. The city may develop, publish, and update from time to time general stormwater pollution guidelines. These guidelines shall at minimum address pollution caused by soil erosion, motor oil, trash, and landscape debris.
