100.32 INSPECTION, SAMPLING, AND RECORD KEEPING AUTHORITY.
Users shall give the following authorities to the WRA and its operating contractor:
1.   Users shall permit authorized representatives or agents of the WRA to enter upon all properties and all parts of the premises or upon properties of users with wastewater discharge permits for the purposes of inspection, sampling, records examination, records copying, or the performance of any of their duties. This shall include the right to set up, on the user's property, such devices as are necessary to conduct sampling, inspection, compliance monitoring, or metering operations as may be required in pursuance of the implementation and enforcement of this chapter.
2.   Where a user has security measures in force which would require proper identification and clearance before entry into their premises, the user shall make necessary arrangements in the security measures so that, upon presentation of suitable identification, personnel from the WRA or operating contractor will be permitted to enter, without delay, for the purposes of performing their specific responsibilities.
3.   All users subject to any of the reporting requirements of this chapter shall maintain copies of reports and records of all information as required in 40 CFR 403.12(o) resulting from any monitoring activities required by this chapter for a minimum of three (3) years and shall make such records available for inspection and copying by the WRA and its operating contractor. This period of retention shall be extended until the completion of any unresolved negotiation, hearing, or litigation involving a purported violation.
