On September 29, 1995, BMRI responded to the Divisions adequacy concerns. On October 25, 19'15 the Division found BMRI's responses to adequacy concern Nos. 1,2, 4, ~, 6, 7, 8, and 10 sufficient. The Division found adequacy concern Nos. 3 and 9 insufficient. The Division deems necessary that now that TR-018 has been approved it sl~otlld be included in Rules 6.4.19 (7} and 6.4.19 (14). All testwork for TR-018 has been completed and was forwarded to the Division on October 19,1995 and February 5,1996 (Sequential Bitch Tests and Humidity Cell Tests, respectively). This testwork does not lead to the conclusion that acid generation may or will occur in the West Pit. Rather, the results of the tests confirm the earlier conclusion that there is no technical basis to suggest that acid generation could occur in the West Pit. To date, BMRI has not received a response from youK~ office regarding the most recent data submittals. On the basis of all test results conducted to date, BMRI does not agree that the West Pit falls under the definition of an Environmental Protection Facility. TR-018 is not an Environmental Protection Facility because there is no evidence of acid mine drainage and designlated chemicals are not stored cr used there. P.O.
