Preliminary Activities Feb n� �' ��1 Z�16 -aoot0 A wet season monitoring program will be conducted after completion of the appropriate application form and payment of fees. The fees are based on whether the monitoring was performed by Mason County Public Health (6 inspections) or by a licensed designer (with 3 quality assurance inspections by Mason County Public Health.) If a licensed designer will be conducting the monitoring program, a site specific monitoring plan will be submitted b'y the designer as part of the overall system design. 2. Site Preparation A minimum of 2 observation ports will be installed in locations representative of a cross section of the proposed drainfield.area. Recommended monitoring port design will consist of a vertically oriented section of 4 inch diameter perforated pipe, wrapped in filter fabric and bedded in clean, washed drainrock or pea-gravel that has been backfilled into a 12-24 inch test hole. The drainpipe should be capped and flagged so as to be easily visible to Public Health staff. 3. Observations and Presentation of Findings Wet season observations will take place during the months of January through March. The frequency and timing of observations will be dependent on site characteristics and on rainfall characteristics that occur during the monitoring period. The designer will submit a minimum of 6 observations along with the NCDC rainfall data for the area during the period of January through March (http://www.ncdc.noaa.gov/oa/mpp/freedata.html). Observations will be recorded with the date and time of the observation and the depth of the water in the pipe. 4.. Analysis of Findings Monitoring results will not be considered valid when the rainfall for the period of observation did not exceed 80% of the 10 year average rainfall for the area during the 6-month period of October through March. 5.
