Who authorizes pretreatment inspectors to enter industrial premises for inspection purposes?

The authorization for pretreatment inspectors to enter industrial premises for inspection purposes comes from local sewer-use ordinances. These ordinances are typically established by municipalities to regulate what can be discharged into the local sewer system, promote compliance with the National Pretreatment Program, and ensure protection of the sewer system and wastewater treatment facilities.

By having these specific local regulations in place, cities can define the scope of inspections, set standards for industrial discharges, and ensure that inspectors have the legal authority to carry out their duties at industrial sites. This localized approach allows for tailored strategies and compliance measures that best fit the unique characteristics of the community’s wastewater system and environmental goals.

Other options like the Environmental Protection Agency and federal laws provide broader regulatory frameworks and guidelines but do not directly grant inspection authority at the local level. State health departments may play a role in overseeing certain health-related aspects but do not specifically authorize entry for sewer inspections, which is primarily under the jurisdiction of local authority as defined by sewer-use ordinances.
