A. General. The Director is authorized to implement and enforce the provisions of this Chapter. The Director will coordinate the implementation and enforcement of this Chapter with other departments of Pierce County government.

B. Treatment BMPs. In the event that a person discharges stormwater into a Municipal Drainage Facility that is not of a quality that complies with County, State, and Federal technology-based requirements, or where determined necessary, water quality-based requirements, the person shall provide necessary source control/stormwater treatment BMPs as required to comply with these requirements. The Manual shall be used to select acceptable technologies. Any facility required to treat stormwater to an acceptable level shall be provided and shall be properly operated and maintained at the user's expense. Detailed engineering plans and specifications showing the treatment facilities shall be submitted to the County for review, and must be acceptable to the County before construction of the facility. The person shall obtain all necessary construction/operating permits from the County. Depending upon size and complexity of the treatment facility, the County may find it necessary to require that the facility be run by a qualified operator. Necessary qualifications shall be determined by the County in each individual case. The review of such plans shall in no way relieve the person from the responsibility of modifying its facility as necessary to produce a stormwater effluent acceptable to the County under the provisions of this Chapter. Upon completion of the treatment facility, the person shall furnish its operations and maintenance procedures to the County for review and approval. Any subsequent significant changes in the treatment facilities or operation and maintenance procedures shall be reported to and be accepted by the County prior to the person's initiation of the changes.

C. Inspection and Sampling. The County may inspect the facilities of any person to determine compliance with the requirements of these regulations. The person shall allow the County to enter upon the premises of the person at all reasonable hours for the purposes of inspection, sampling, or records examination. The County shall have the right to inspect and copy any of the person's records that are required by, or that relate to, compliance with the terms and conditions of these regulations. The County shall have the right to set up on the person's property such devices as are necessary to conduct sampling, inspection, compliance monitoring, and/or metering operations.

D. Confidential Information. Information and data furnished to the County with respect to the nature and frequency of discharge into the stormwater system shall be available to the public or to other governmental agencies without restriction unless the person specifically requests and is able to demonstrate to the satisfaction of the Director that the release of such information would divulge information, processes, or methods of production entitled to protection as trade secrets or proprietary information of the person. When requested by a person furnishing a report, the portions of a report or other information which may disclose trade secrets or secret processes shall not be made available for inspection by the public but shall be made available upon written request to governmental agencies for uses related to these regulations, NPDES Permit and/or other programs as amended; however such portions of a report or other information shall be available for use by the County, the State, or any other public agency in enforcement proceedings involving the person furnishing the report. The constituents and characteristics of the stormwater will not be recognized as confidential information. Information accepted by the County as confidential shall not be transmitted to any governmental agency or to the general public by the Director until and unless a ten day notification is given to the person.
