Title 33 › Chapter CHAPTER 26— - WATER POLLUTION PREVENTION AND CONTROL › Subchapter SUBCHAPTER III— - STANDARDS AND ENFORCEMENT › § 1318

Summary

Requires the federal Administrator to make the owner or operator of any point source keep records, send reports, install and use monitoring tools, take samples of discharges, and give other needed information when it helps set or enforce pollution limits, check for violations, or run permit and other programs under the chapter. The Administrator or an authorized representative may show ID and enter places with those sources, look at and copy records, check monitoring equipment, and take samples at reasonable times. Most effluent data and related records must be public. Other business information can be kept secret if it truly reveals trade secrets, under section 1905 of title 18. An authorized representative who willfully discloses such protected information can be fined up to $1,000 or jailed up to 1 year, or both. States may use their own inspection rules if the Administrator finds them as protective as federal rules (not for federal facilities). Any authorized congressional committee can get reported or obtained information on written request.

Any authorized representative of the Administrator (including an authorized contractor acting as a representative of the Administrator) who knowingly or willfully publishes, divulges, discloses, or makes known in any manner or to any extent not authorized by law any information which is required to be considered confidential under this subsection shall be fined not more than $1,000 or imprisoned not more than 1 year, or both.

(c)Each State may develop and submit to the Administrator procedures under State law for inspection, monitoring, and entry with respect to point sources located in such State. If the Administrator finds that the procedures and the law of any State relating to inspection, monitoring, and entry are applicable to at least the same extent as those required by this section, such State is authorized to apply and enforce its procedures for inspection, monitoring, and entry with respect to point sources located in such State (except with respect to point sources owned or operated by the United States).
(d)Notwithstanding any limitation contained in this section or any other provision of law, all information reported to or otherwise obtained by the Administrator (or any representative of the Administrator) under this chapter shall be made available, upon written request of any duly authorized committee of Congress, to such committee.
