For example,materials should be stored and handled in covered areas whenever possible to prevent contact with smrmwamr fuels and other chemicals should be stored within berms or secondary containment devices to prevent leaks and spills from entering stormwater runoff. 3) Freston and Sediment Controls-Describe BMPs that will be used to reduce erosion and prevent sediment delivery to State waters.

Impacted Stream Segments:For this general permit,any existing or new operation that discharges to a segment that is lined on the Divisions 303(d)list of impacted stream segmout may require a an Individual permit The 303(d)segments are segments in which water quality standards for one or more pollwants are exceeded For most ifnot all,oft he operation that discharge under this perm/:,there are no monitoring data to vet*the expectation that these discharges will not impact a listed segment Therefore,for those facilities that discharge process water to segments on the 303(d)list the pennitrees will be required to perform a one-see analysis upon commencement of discharge for the listed parameters ofconcene to cotlfrm that stream standards for these pa ametersarenot'accededin the discharge concentrations.

W(magnesite),X(diatomite), Y Jade),2(novoculite),and AF(tripoli). 2. Discussion of Limitations: a Exceptions to Federal Limits: The 40 CFR 436 includes some effluent limitations,which are not as snick as,those lined hart Par example,the phosphate ruetTSS land is less strict and formany of the subcategories,which state'Smdischarge of process wastewater.'an exemption to that limit is provided during certain pregoitarion events and br conjunction with other conditions. However,this permit does not indude these relaxed limits. This is a general permit,designed to cover the widest possible range offacilities with similar wastewater characteristics. In effectively achieving this broad coverage,the permit must also be relatively simple Therefore,some of the more individualistic or complex permit limitations are not included in this permit The Division does nor believe that there ore a s4joentty large number ofsucb facilities is Colorado to warrant including the exemptions in this geners/permit (fa permiaee wishes to take advantage althea exemptions.the permntee must apply for an individual permit. b.

In addition,the plan shall describe the best managernentpractices (MI's)which will be used to reduce the polhaants in stop nvcrzer discharges from the mining sire Some activities required under the SWMP may already be in place However,the SWMP will require the pe rmiuee to coonduate these activities with any necessary new activities in an orderly manner,so that the result is the reduction or elimination ofpollutants reaching state wntmfrom areas not limited byeement!imitations Facilities nuns implencis the provisions of the SWMP required under this part as a condition ofthis permit It is the peminee's respon ibdtry to notify the Colorado Division of-Mistrals and Geology(forme ly she Colorado Mined land Reclamation Division)ofany significant changes at their site resulting fiomMebrrplaneate:ioatoftheMOM, This it so that the Division of Minerals and Geology may review the SWMP and incorporate any potential revisions Into the faciiey's reclamation permit which might be needed The SWMP shad iwc!>.de the following items,at a minimum: a.
