'~\ r ~~, ~,~\ Q~ 4 ~~ r~'' ~ ~J The fuel tank at CRDA #1 mentioned on p, 171 and nearby topsoil pile illustrated on Exhibit 9B appear to be outside of the current surface water and sediment control system. If true, revision,of the permit is required proposing sediment control measures or an exemption, The narrative on page 1790 should be revised to include the following: 1, As long as CRDA #1 is "under construction" ditches may not be in their final position, 2. A71 ditches for CRDA #7, however, whether in final or tem pos' are esi led and will be maintained to safel c rry 100-year, 24-hour events and will be equipped with en diss~pa or r#pra sary to insure stability in their current position. ~~~. Rule 2.05.4 (a) through (g) We suggest that paragraph 1 on p. 186 be deleted since pfC it is contradicted by subsequent narrative. Requirements for CRDA #2 and the Roadside Refuse Area need to be added big to Figure 2.05.4A. (b) The cost figure given in the first paragraph on p, 186 should be Ll(< revised to reflect the current cost estimate and the current reclamation cost estimate should be placed in Appendix U. Rule 2,05.6 {3){b)(ii} Mention is made on pp 206-207 of the use of flocculants but none are mentioned specifically. MLRD and WOCD both require ~,;~ identification of any such chemicals whose use may affect the nature of the water being discharged, information about them, e.g, material safety data sheets, and a description of how these chemicals are administered. The probable hydrologic consequences of the use of these flocCUTants should should also be covered in the permit application package. (3)(b)(iv) Roadside/Cameo Mine's NPDES Permit expired June 30, 1990, .~-c The mine must furnish evidence of the renewal of this permit and that the WQCD is aware of the mine's use of flocculants for treatment of surface runoff and mine water prior to its discharge, Table 2.05.6A on p, 211 is in error. Effluent limitations in the ~<< Roadside/Cameo NPDES permit do not inciude manganese, include greater TSS allowances, but impose oil and grease limitations. The monitoring plan described on p. 207 does not indicate when the AHR U`~ will be submitted. Please specify an annual submittal date. The organization of Section 2.05.6 of the permit application is confusing and neeas improvement. Considerable subsidence information is included on page 214 through 223, preceding the discussion of parks and historic places on page 223. Thus it is separated from other subsidence aiscussion beginning on page 224. Organization of the document would be improved by consolidating the subsiaence narrative. 5590E/scg -9-
