- (a) The owner of a PWS who is required to take repeat samples and who wishes to establish alternative sampling locations believed to be more representative of a likely pathway of contamination shall submit a proposed plan in writing to the department for approval. Submission of a proposed plan shall not extend the time limit for taking the samples established in Env-Dw 709.15(a) or (b).
(b) A proposed plan submitted under (a) above shall include:
- (1) The system’s name and PWS identifier;
- (2) The name, mailing address, daytime telephone number including area code, and e-mail address for the system’s representative who can be contacted by the department regarding the request;
- (3) If the owner is proposing alternative fixed locations, the specific locations proposed; and
- (4) If the owner is proposing situation-based sampling, a proposed standard operating procedure (SOP) for determining the location where the repeat samples will be taken to verify and determine the extent of potential contamination of the distribution system area based on the specific situation.
- (c) The department shall respond to the proposed plan in writing. If the plan is not approved, the department’s response shall specify the reason(s) why.
- (d) The department shall approve the proposed plan if the department determines that the proposed alternative locations or SOP will result in samples that are more likely to verify and determine the extent of potential contamination of the distribution system area based on specific situations than the existing locations or SOP, as applicable.
- (e) If the department determines that the proposed alternative locations or SOP would be acceptable with modifications, the department shall inform the owner of such modifications. If the department makes modifications, the PWS owner shall either implement the plan as modified or take samples in the location(s) specified in Env-Dw 709.15.
