These regulations aim to protect surface water from pollutant discharges. They describe allowable discharges in the state that are subject to permits, discharges which may be made without permits, as well as discharges that are prohibited. The regulations require reports of the identity, amount, frequency, concentration, temperature, and other discharge characteristics, and establish rules for toxic discharges as well as maximum daily discharge limitations. Some exemptions to stated requirements, including exemptions for small businesses, are noted in the regulations. General permit applications exist for discharges associated with industrial activity, construction activity, and non-contact cooling water discharges.
