A waste water characterization shall be provided by any facility required to register under both § 51.31(C) and (D) of these rules and regulations and each facility shall be subject to the following.
(A) A waste water characterization for each on-site disposal system shall be provided by an independent, qualified laboratory using standard EPA methods appropriate for the testing and analysis being performed. In the absence of a liquid waste water sample, soils from the waste water system may be used to determine waste water characterization upon prior written approval from the Health Department.
(B) Minimum testing required shall be directly related to the hazardous and/or toxic substances identified at the facility. Tests may include, but are not limited to, the following analyses:
(1) Total toxic organics (volatile organic chemicals, semi-volatile organic chemicals, pesticides); and
(2) Heavy metals (as listed in federal and/or state primary drinking water standards).
(C) Sampling method requirements.
(1) All sampling and analysis conducted to comply with this section shall be performed in accordance with 40 C.F.R. part 136, as amended or methodology approved in writing by the Health Department.
(2) Samples shall be representative of facility effluent discharges.
(3) Practices such as dilution or treatment that change the representative facility effluent discharge are a violation of these rules and regulations.
(4) The individual who obtains the waste water sample shall certify compliance with these sampling method requirements.
(D) Chain of custody. Chain of custody procedures shall be followed on all waste water sampling, handling and testing procedures.
(E) For facilities subject to this section, an initial waste water characterization may be required after a system is placed into service. No further waste water characterization shall be submitted unless deemed necessary by the Health Department. The Health Department may require additional testing for a facility if the Health Department has a rational basis for doing so based upon inspection, complaint, an operational change at the facility or contamination of the waste water system or ground water in the area.
