Summary
Surprise requires anyone conducting significant construction activity, defined as one acre or more of land disturbance, to keep erosion and sediment controls in place and maintained for the life of the project. The rule is enforced by the city engineer under the storm water ordinance, Chapter 58, Article VI.
Any person operating under a construction storm water permit issued by the EPA or ADEQ shall not cause or contribute to any condition that may result in a violation of any storm water permit issued by the city. Such person shall undertake any and all BMPs necessary to: minimize to the MEP the potential of any pollutant being discharged from the construction site; provide protection from accidental discharge of pollutants to the public storm water system; ensure sufficient erosion and sediment controls are in place and adequately maintained; ensure construction materials are handled and stored in a manner such as to reduce to the MEP the discharge of pollutants associated with such materials; and control and properly dispose of any waste that may cause adverse impacts to water quality (i.e. discarded building materials, concrete truck washout, chemicals, litter, sanitary waste, etc.).
Full Breakdown
Under Sec. 58-492 of the Surprise storm water ordinance, any person engaged in "significant construction activities" (a land disturbance of one acre or more, or a smaller disturbance that is part of a larger common plan of development or sale reaching one acre) who is required by the EPA or ADEQ to file a Notice of Intent under an NPDES or AZPDES construction storm water permit must give the city engineer copies of that NOI and any resulting authorization, plus a copy of the Storm Water Pollution Prevention Plan (SWPPP) covering all contiguous land under common ownership before any grading, construction or grubbing permit is issued.
" Construction materials must be stored to reduce pollutant discharge, and waste such as concrete truck washout, discarded building material, chemicals, litter and sanitary waste must be properly disposed of. If the city engineer orders an additional BMP during construction, the responsible party can petition in writing within 14 calendar days for reconsideration, setting out reasons and proposed alternatives; the city engineer must act within 30 calendar days, and that decision can be appealed to the city manager within five business days. The city manager may grant exceptions where necessary to maintain health and sanitation standards.
Violations & Fines
Failure to maintain required erosion and sediment controls, or any discharge that violates the city's storm water permit, is enforced under Sec. 58-548: the city may first issue a notice of opportunity to correct, then a notice of violation if the problem persists, with each day beyond the 14th day after the notice a separate violation. Intentional or negligent violations are a class 1 misdemeanor, and the city may also issue civil citations, revoke permits, or assess the property owner for the city's surveillance and remediation costs.
