(a) Each nonresidential user may be required to construct and maintain one or more control manholes, access points or measuring devices to facilitate observation, measurement and sampling of the wastes, including domestic sewage.
(b) When required by the Authority, control manholes, access facilities or any necessary meters shall be located and built in a manner acceptable to the Authority.
(1) If measuring devices are to be permanently installed, they shall be of a type acceptable to the Authority.
(2) Plans for the installation of the control manholes or access facilities and related equipment shall be approved by the Authority prior to the beginning of construction.
(3) The structures and facilities shall be installed by the owner at his or her expense and maintained by him or her so as to be safe and accessible at all times.
(c) All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with the latest edition of Standard Methods and in accordance with 40 CFR Part 136, entitled Guidelines Establishing Test Procedures for Analysis of Pollutants, and shall be determined at the control manhole provided or upon suitable samples taken at such control manhole.
(d) Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewerage works and to determine the existence of hazards to life, limb, and property.
(1) The particular analysis involved will determine whether a twenty-four hour composite of all outfalls of a premises is appropriate or whether a grab sample or samples should be taken.
(2) Normally, but not always, BOD and suspended solids (SS) analyses are obtained from twenty-four hour composites of all outfalls, whereas pHs are determined from periodic grab samples.
(e) If necessary, the Authority shall have the right to enter and set up on a nonresidential user's property such devices as are necessary to conduct a gauging and sampling operation and the right to begin such operation without advance notice to the owner. While performing such work, the Authority's personnel will observe all safety rules applicable to the premises, as established by the property owner.
