COLORADO DEPARTMENT OF I1F..1L77i - Warn Quality Control Division Rnrionale -Page I2 Permit No. COR-04001D0 additional information, reporting and st~ormwater quality rorttroLs on a case-by-cast basis, as needed. The Division has meanlintd the definition of /wttivr mining operations by removing the clause 'which have an id~ntifiabk owner or operator'. Sine, to the Division's knowledge, there is ro land in the Stare of Colorado for which ~herev nor an itkmifrable owner., the Division feels that this is an unnecessary romplication of the definition. Inactive mines ate defined simply as mining sites that arc nor being aaivrly mined. There Cr no invent to make the definition more inclusive t/utn the definition in EPA's rcgulationt. C. Submittal of Stosmwater Management Plant for Review and Approval Several romments were rcreivrd regarding the submittal of Stormwatr Marutgement Plans (SWMPsJ ra the Division for miew and approHaL Farsors cited in arguing against requiring submittal and approval of SWMPs were: I) limited Division rcsourres to luuuile all the documents; 2) the Division acknowledganem that not all documems would be reviewed,• and 3J tiu burden of reproducing information already comained in the CDMG Reclamation Plan /n reviewing the issue, the Division concluded that for metal mining operations SWMP developmem and implemematian is still necessary, but submittal would only be required upon speck wrinen request by the Division. Certhcntion that the SWMP leas been completed and implemented is now required. 1. Certif~caNon of SWMP Completion and Implementation: For active mining operations erirfing on October I , 1992, rnr~aation of SWMP romplaion and implementation is required to be submitted to the Division ar soon as possible but no later than the anniversary date of their Mined Land Reclamation pmnit that falls between July 1, 1993 and June 30, I994. 77te cm~eation date for SWMP implementation has been roordinated with the anniversary date of the reclamation permit to facilitate the review by CDMG and potential madhcation gf reclmnation plans. Ibis coordination with the anniversary date will spread out the potemia! impact on the CDMG. For new active facilities (beginning operations after October I, 1992), and for all other active facilities applying after July I, 1993, the SWMP shall be prepared prior to applying for coverage under the general permit. For inactive mining operations, applying before July 1, 1994, rert~cation of SWMP completion and implementation is required ro be submitted ro the Division as soon as possible but na later than July 1, 1994. For those applying after July I , 1994, the SWMP shall be prepared prior to applying for coverage under the general permit. 2. Contents and Formal of Stotmwat'er Management Plata: Some activities required under the SWMP may already be in plane. However, then SWMP will require the perminee to coordiruut these activities with any nenssary new activities in an orderly manner, so that the rrsuh is the reduction or elimination of poUutams reaching state waters from arras not limited by er/Iuent limitations. The SWMP may rely upon information detrlopeod for abet similar pollution corurol programs such as the SPCC (Spill Prevrmion Control and Countermeasures) plan or the Mined Land Reclamation Plan. Appropriae portions of there othn• plans may be inrorporated in the SWMP by referenre, as long as a complete SWMP tnrr be reproducni and submitted to the requesting agenry within the time frame specified in the request. Those portions of the rcfercnrnd documents cons! be included in the submittal. The SWMP must also be readily available to an on-site inspector. 3. Coordination With CDMG: It is the petmiaee's responsibility to notes the CDMG of any changes at tbeir sire resulting from the implementation of the SWMP. This is so that tlu CDMG may review the SWMP and inrorporate any potemial revisions imo the facility's rcc4unation permit which might be needed. Perminees are asked to verify that their reclamation permit rnatahes thdr SWMP. Such information is usually romainrd
