Mr. Charlie McNeil -2- May 15, 1992 <br /> Crystal Springs Coal , Inc. <br /> Also enclosed are copies of Attachments A and B from NOVs C-91-016 and <br /> C-91-017. Attachment A identifies the portion of the operation to which these <br /> notices apply and Attachment B lists the specific abatement steps necessary to <br /> abate NOVs 16 and 17. The abatement steps for NOVs 16 and 17 are reiterated <br /> below: <br /> A. Steps necessary to abate Notice of Violation C-91-016: <br /> 1 . Riprap the following culvert outfalls and ditch relief drains in <br /> compliance with approved plan: <br /> a) Ditch Drain RD-5, Road C <br /> b) Culvert D-3 <br /> c) Culvert B-3 <br /> d) Culvert G-13 <br /> e) Culvert G-4 <br /> f) Double Culvert set on Road F, Sta. 83+00 <br /> g) Culvert F-5N <br /> h) Culvert F-2 <br /> i ) Culvert E-3 <br /> 2. Clean out/excavate the following culvert inlets : <br /> a) Culvert D-3 <br /> b) Culvert G-12 <br /> c) Culvert G-8 <br /> 3. Clean out ditch sediment in the ephemeral channel below ditch relief <br /> drain RD-4, Road F. <br /> 4. Reset culvert at 83+00, Road F, to prevent outfall erosion. <br /> B. Steps necessary to abate Notice of Violation C-91-017: <br /> 1 . Repair/reconstruct all road ditch segments as necessary to comply with <br /> approved plan, including installation of riprap checks . As a <br /> temporary measure , 18-inch-high berms may be substituted for ditches <br /> where solid bedrock precludes ditch excavation or where natural <br /> erosion of upslope material prevents maintenance of an inside ditch <br /> (e.g. , Road F, below Culvert F-1 ) . Berms shall be used to prevent <br /> uncontrolled drainage over the outslope and shall be tied into dips or <br /> water bars as necessary to direct flow to the inside of the roadway to <br /> insure that drainage is discharged at properly stabilized, designed <br /> ditch relief drains or culvert outfalls . Berms shall not be used <br /> where snow removal would push them over the outslope . <br /> 2 . Measures shall be taken to insure that drainage from Road C is not <br /> diverted down the pilot road. Water bars shall be installed along the <br /> pilot road at a 100-foot spacing, draining to the outside. <br />
