Public Notice Chances <br />Fiti,e aommetu litters were rcttkwd by the Division during the 30 day pubUc comment perkod. Several clarifications <br />and changes were made to the draft permit based on these cornnrents. <br />1. SeNerol commenttrs espnssed conttrn with the need to submit a copy of the SWMP to the CDMG. A major <br />eonttrn was that other states and EPA ngienr xrrr not requiring submittal of the plans. <br />Jn miewing the issue, the Division concluded that, for fatilitiu msrrcd under the Sand and Gratin genera! <br />Permit. Plan deNelapnent arrd implanentation it still rurorssmy, but rrrbmittal would only be rrqukrrd upon <br />spedjic written regrrert by the Dlvirion or CDMG. One major benefu of thks approach is that Division and <br />f~MG resouroa cart be hater uHGzed in mnduaing field inspcaions and checking program implementatkon <br />The information collected will then allow Proper progmm~ atljusnnents ar permit renewal (in five years). <br />Coordination with CDMG will be through the due date of ear~earion that the SWMP has been preparrd and <br />implemented, whidr is bared on the due daft for the facAity's annual reclamation pnmkt report to CDMG <br />during July 1, 1993 to June 30, 1994. /t ks assumed that SWMP preparation may generate the nerd for <br />technical rrvisrons to the fackliry's reclamation permit through (9MG, and so the SWMP cert~catkon due <br />dares arc spread throughout the year ro stagger the ®MG's xarkload <br />For any fadliries covnrd under this permit which do not also have a rcdtuwtion pernrit.under CDMG, the <br />SWMP earifitntion of rnmpktion and rmplonauation is due by July 1, 1993. <br />2. One commenter requested the rernova! of the annua! reporting requiranerus jot srormwater duckwrges. Given <br />that submittal of the SWMP is no longer automatic, the Division believes that the best overall method of <br />determining aomp/kantt by the regulated twmmutriry, without kmposing stormwarer monitoring requirements, is <br />submittal of an annual report. The rrporting nquirrments bast been scaled back to rcflcct the fan that the <br />Divvion wiII not haHe a copy of the SR'MP on hand (m mart tnserJ. <br />In addition, the permit has been clarifud to show that no annual reports will be dui before February 15, <br />1994. The pernrit[ee's cerslfitaation wiII indiaarc nc~ esaa due dart for the Jirst annual report. <br />3. In response to marry rnmmenu from the mnstrvtsion mid mining cammunkry, thv permit rnNerage has been <br />broadened to include concrete batch plane. Prottss water dirtdrarges from rnncrae batch plants (including <br />trunk wash woterJ will be srrbjea ro the numeric limits ar limed in Scaian V.A.1.a of the Rationale. <br />4. More dttail has been addrld to the aomprdvsritir ittrpeaion -equironents, for mnsistenry with the Division's <br />other starorwater general pmnku. <br />There wen streral other aommenu rcttived by the Division on this permit. The issues raised Katie been addressed in <br />individual letters to the commenters. This peroit is subject to nrrewa! in September, 1997.
