A. The hydrogeologic assessment may be submitted by a state of Washington licensed hydrogeologist, or professional engineer with a strong background in geology as demonstrated by course work from an accredited college or university. Persons who believe they are qualified to conduct a hydrogeologic assessment may petition the TPCHD for consent.
B. The hydrogeologic assessment shall include, but is not limited to:
1. Information sources;
2. Geologic setting: include well logs or borings used to identify information;
3. Background water quality;
4. Ground water elevations;
5. Location/depth to perched water tables;
6. Recharge potential of facility site (permeability/transmissivity);
7. Ground water flow direction and gradient;
8. Currently available data on wells located within 1,000 feet of site;
9. Currently available data on any spring within 1,000 feet of site;
10. Surface water location and recharge potential;
11. Water source supply to facility (e.g., high capacity well);
12. Any sampling schedules necessary;
13. Discussion of the effects of the proposed project on the ground water resource;
14. Other information as required by the TPCHD.
C. Uses requiring a hydrogeologic assessment may be conditioned or denied based upon the TPCHD’s evaluation of the hydrogeologic assessment. Any project denied a permit based upon the Tacoma-Pierce County Health Department’s evaluation of the hydrogeologic assessment shall receive a written explanation of the reason(s) for denial and an explanation of measures required, if any, to comply with these regulations.
