Comparison: State vs. Federal
• Rules. Iowa has adopted EPA's pretreatment standards under the Clean Water Act, Sections 301, 306, and 307. However, DNR may adopt a more restrictive effluent limitation for a particular discharge as necessary on a case-by-case basis. See the national section PRETREATMENT STANDARDS and contact DNR for more information.
DNR has also established standards for the commercial cleaning of and the disposal of waste from private waste facilities and septic tanks, and licensing requirements and procedures.
• Administration and enforcement. DNR's Water Quality Bureau administers the state's water quality program and enforces pretreatment requirements in Iowa.
DNR's Customer Service Bureau licenses commercial pumpers of septic tanks. Although DNR is responsible for licensing and regulation of commercial septic tank cleaners, county boards of health are responsible for enforcement of the regulation.
