General Comments. The presentation and format of the AHR data is excellent and aids in <br />review of the data. <br />1. As per Trapper's response dated June 2, 1992, a commitment to spot wells GP-7 and <br />GP-8 on the 1992 AHR map was established. Neither well appears to be spotted. <br />Please add these wells to the AHR map. Also, in the future, please insure that previ- <br />ous year commitments are handled for future submittals. <br />2. Please update the 1993 AHR map with the most recent topography. This will assist in <br />the coming years in relating pits to well locations and more accurately tie the data to <br />the map. <br />Trapper Response: <br />A. 1.-2. As we discussed, the AHR trap will be updated with new topography in the next <br />annual report submittal in March, 1994. Wells GP-7 and GP-8 will also be spot- <br />ted on the AHR map at that time. <br />CDMG Comment: <br />A. 3. In the weather data summary table 1992 summed data appears to be 1991 input data. <br />Please inspect this table for accuracy and re-submit two copies if necessary. <br />A. 4. What does percent PTD mean represent in the weather data summary? It appears this <br />data is also in error due to potential problems referred to in question 3. Please clar- <br />ify. <br />Trapper Response: <br />A. 3.~. A revised weather data summary table is enclosed and should replace the existing <br />table. In the existing table the "1942 Sum" and "?o PTD Mean" row summaries <br />erroneously included 1991 data rather than 1992 data. <br />CDMG Comment: <br />5. How is the spring above Johnson Pond No. 6 sampled? Field inspection seems to indi- <br />cate the need to choose a downstream point where a composite value can be obtained for <br />the numerous springs that emtninate in this area. Please provide discussion. <br />Trapoer Response: <br />A. 5. The spring above Johnson Pond No. 6 is sampled at a point downstream where the <br />R~~ springs come together to form a single flow. However, even at the composite flow <br />~~~~~\ ~pomt, the flow volume has typically been less than the 5 GPM sample threshold limit. <br />Q~ <br />
