Discharge Points: F. Facility Flows: III. RECEIVING STREAM: 001 - Stormwater runoff from excavation cell, with placement of waters to a retention sedimentation basin, pumped to a ditch flowing to a unnamed tributary to Government Creek. 001 -Design flow of 400 gpm and a maximum flow of 400 gpm. Sedimentation volume will vary according to the extent of completion of cell excavation. A. Identification, Classification and Standards 1. Identification: The discharge from the Estes Gulch Disposal construction site five miles north of Rifle, Colorado on U.S. Highway 13 will flow to a unnamed tributary to Government Creek. Government Creek is included in Segment 4, of the Lower Colorado River Sub -basin, of the Lower Colorado River Basin. 2. Classification: Segment 4 is classified for the following existing uses: Aquatic Life, Class 2 (Cold); Recreation, Class 2; Agriculture. 3. Numeric Standards: The complete list of standards which have been assigned in accordance with the above classification can be found in 3.7.0, Classifications and Numeric Standards for the Lower Colorado River Basin (5 CCR 1002-8), as amended February 4, 1991. It should be noted that this facility does not discharge pollutants which are limited by water quality standards with the exception of pH. B. Receiving Water Data 1. Stream Low Flow: Not applicable; effluent limitations are not flow based. 2. Downstream Water Supplies: There are no known surface water supplies located within five miles of project area. 3. Antidegradation Review: Since segment 4 is classified as Aquatic Life Cold, Class 2; Recreation, Class 2; an antidegradation review is not required pursuant to section 3.1.8(1)(b) of the Basic Standards and Methodologies for Surface Water. COLORADO DEPARTMENT OF HEALTH, Water Quality Control Division Rationale - Page 3. Permit Number COG -070206 IV. FACILITY DESCRIPTION: Industry Description The MK -Ferguson construction will be site preparation and primary excavation, for an engineered disposal embankment for uranium mill tailings produced from the cleanup of a former uranium processing site, as shown in Exhibit A-1, Page 22 of the permit. This activity is being conducted under a cooperative agreement between the U.S.Department of Energy and the State of Colorado Department of Health. Construction will begin May of 1992, with estimated life activity of one and one half years. Discharge from this site will be from the stormwater runoff which may accumulate in the cell excavation and retention basin prior to placement of contaminated materials. There has been no water analyzed at this time. Outfall point 001 has been indicated as stormwater runnoff from the excavation cell with an estimated pumped flow rate of 4,770 gpd as shown in Exhibit A-2, Page 23, of the permit. Flow from outfall point 001 will enter the sedimentation basin which will be used to regulate and minimize discharge of suspended sediment. Water shall be pumped from the sedimentation pond, at a 400 gpm rate to a ditch flowing to a unnamed tributary to Government Creek. Government Creek is approximately 3,000 feet from the facility discharge. Flow will be measured from the proposed pump capacity curve. Polymer flocculants will be used if necessary to treat water prior to discharge. The site is not located within one mile of a landfill, or any mine or mill tailings. There are no water supply intakes within five miles of this facility. There will be bulk storage of diesel fuel on site.

Change in Discharge The permittee shall inform the Division (Permits and Enforcement Section) in writing of any intent to construct, install, or alter any process, facility, or activity that is likely to result in a new or altered discharge and shall furnish the Division such plans and specifications which the Division deems reasonably necessary to evaluate the effect on the discharge and receiving stream. The permittee shall submit this notice within two (2) weeks after making a determination to perform the type of activity referred to in the preceding paragraph. Process modifications include, but are not limited to, the introduction of any new pollutant not previously identified in the permit, or any other modifications which may result ins discharge of a quantity or quality different from that which was applied for. Following such notice, the permittee shall be required to submit a new CDPS application and the permit may be modified to specify and limit any pollutants not previously limited, if the new or altered discharge might be inconsistent with the conditions of the existing permit. In no case shall the permittee implement such change without first notifying the Division. 2. Special Notifications - Definitions a) Bypass: The intentional diversion of waste streams from any portion of a treatment facility. b) Severe Property Damage: Substantial physical damage to property at the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. It does not mean economic loss caused by delays in production. c) Spill: An unintentional release of solid or liquid material which may cause pollution of state waters. d) Upset: An exceptional incident in which there is unintentional and temporary noncompliance with permit effluent limitations because of factors beyond the reasonable control of the permittee. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventative maintenance, or careless or improper operation. PART II Page 12 PERMIT NO.: COG -070000 A. MANAGEMENT REQUIREMENTS (CONTINUED) 4. Submission of Incorrect or Incomplete Information Where the permittee failed to submit any relevant facts in a permit application, or submitted incorrect information in a permit application or report to the Division, the permittee shall promptly submit the relevant application information which was not submited or any additional information needed to correct any erroneous information previously submitted. 5. Bypass The permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, but if and only if it is for essential maintenance to assure efficient operation. Bypass is prohibited, and the Division may take enforcement action against a permittee for bypass, unless: a) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage; and b) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if the permittee could have installed adequate backup equipment to prevent a bypass which occurred during normal periods of equipment downtime or preventative maintenance; and c) The permittee submitted notices as required in "Bypass Notification", Part II.A.6. 6. Bypass Notification If the permittee knows in advance of the need for a bypass, a notice shall be submitted, at least ten days before the date of the bypass, to the Division and the Environmental Protection Agency (EPA). The bypass shall be subject to Division approval and limitations imposed by the Division and EPA. PART II Page 14 PERMIT NO.: COG -070000 A. MANAGEMENT REQUIREMENTS (CONTINUED) 9. Minimization of Adverse Impact The permittee shall take all reasonable steps to minimize any adverse impact to waters of the State resulting from noncompliance with any effluent limitations specified in this permit, including such accelerated or additional monitoring as necessary to determine the nature and impact of the noncomplying discharge. 10. Discharge Point Any discharge to .the waters of the State from a point source other than.specifically authorized by this permit is prohibited. 11. Reduction, Loss, or Failure of Treatment Facility The permittee has the duty to halt or reduce any activity if necessary to maintain compliance with the effluent limitations of the permit. Upon reduction, loss, or failure of the treatment facility, the permittee shall, to the extent necessary to maintain compliance with its permit, control production, or all discharges, or both until the facility is restored or an alternative method of treatment is provided. This provision for example, applies to power failures, unless an alternative power source sufficient to operate the wastewater control facilities is provided. It shall not be a defense for a permittee in an enforcement action that it would be necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this permit. 12. Proper Operation and Maintenance The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions of this permit. Proper operation and maintenance includes effective performance, adequate funding, adequate operator staffing and training, and adequate laboratory and process controls, including appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems only when necessary to achieve compliance with the conditions of the permit. 13.

The General Permit system for regulating discharges from the construction operations has worked well for the State. In the past discharges from oil and gasoline groundwater clean-ups have been included under this general permit. After a review of this procedure a decision was made to discontinue this allowance. Such facilities do not fall under the definition of Construction Dewatering operations and thus can not be regulated under this permit. Moat of the other conditions of the original permit and rationale are still applicable, a copy is attached for reference. The most significant change is that of the definition of the 30 day average limitation for total suspended solids. The previous permit used a definition based upon the mean of a minimum of three samples while the new definition is the mean of all samples collected. The significance of this change is that if only one sample is collected in a month, compliance with the 30 mg/1 limit is required. Reauthorization Part I.A.1 of the permit specifies that authorization to discharge under this general permit will expire on September 30, 1993, thus facilities wishing continual coverage under this permit must reapply by April 1, 1993. Patricia Nelson Maureen Dudley June 15, 1988 Public Notice Comments This permit, as originally public noticed on July 15, 1988, contained limitations and monitoring requirements for oil and gas groundwater clean-up operations. EPA commented that inclusion of such clean-ups was beyond the scope of this general permit. After review the Division concluded that this was true. Thus the general permit has been revised; the requirements for clean-up operations currently certified under this general will be converted to individual permits during the recertification stage. Patricia Nelson August 17, 1988 RATIONALE - Page 2 Permit No: COG -070000 Coverage Under This Permit An applicant wishing to discharge under the general permit must first supply background information on the activity. The permit provides thirty (30) days for the Division to deny discharge authorization or request additional information. - This permit does not constitute authorization under the provisions of 33 U.S.C. 1344 (Section 404 of the Clean Water Act), of any stream dredging or filling operations. The following list shows some of the criteria under which an individual permit may be required instead of a general permit. 1. Proximity of the operation to a landfill or mine and mill tailings; 2. Evidence of non-compliance under a previous permit for the operation; 3. Presence of downstream drinking water intakes; 4. Preservation of high quality water; 5. Addition of flocculants (settling agents or chemical additives) to water prior to discharge. b. The use of land application as a means of discharge. 7. The bulk storage or use of chemicals on site that could be discharged through the construction dewatering operation. Permit Rationale The owner, operator and/or authorized agent for a facility desiring to discharge shall submit an application as provided by the Water Quality Control_ Division. This application will be evaluated. If the general permit is applicable to the operation, then a rationale will be developed and the facility will be certified under the general permit. The certification rationale shall include at a minimum the name and address of the contact person, a discussion of compliance under the previous permit, if applicable, the receiving water for the discharge, number of discharge points, a determination of the need for salinity monitoring and the expiration date of the general permit certification for the specific facility. If after evaluation of the application, it is found that the general permit is not applicable to the operation,' then the application will be processed as an individual permit. For an individual permit, up to 130 days will be required to process the application and issue the permit. In this case discharge cannot take place until the permit is issued and becomes effective. The general permit itself will contain the effluent limitations and the monitoring requirements for the permitted discharge' points. The following text details the rationale for the conditions of the general permit. RATIONALE - Page 4 Permit No: COG -070000 Oil and Grease Oil and Grease may be present in the discharge as the result of pump lubricant contamination or contaminated extraneous runoff entering the discharge. A limitation of 10 mg/1 for Oil and Grease is recommended based on the Colorado Regulations for Effluent Limitations. This level can generally be attained by conventional oil skimming methods or a submerged overflow. Further, at 10 mg/i of Oil and Grease a visible sheen normally becomes evident. Monitoring shall be weekly for Oil and Grease. 21.1 The pH range of 6.5-9.0 for state water quality standards (WQS) is the effluent limitation appropriate for this permit. Though some stream segments in the state have a WQS of 6.0-9.0, a sufficient number of streams have the more stringent limitation of 6.5-9.0 thus warranting imposition of this Limitation. Waters normally encountered are at a pH of 7.0-8.0. Natural surface and groundwaters in a few locations in the state will not be within these limits and a facility at such a location will very likely be considered an abnormal operation and therefore required to obtain an individual permit. Flow Flow monitoring will be required under this permit. Flow volumes will be determined by pump rate or other methods that the Division finds acceptable. The frequency of flow monitoring is discussed in the body of the permit. There will be no limitation on the flow volume discharged under the general permit. Flocculants Because of a wide variety of available chemical flocculants, the use of such settling aids must be subject to prior approval by the permit issuing authority. However, since Lime and alum are the most Frequently used aids for settling and typically their use results in no significant effect on other pollutant parameters, permission for their use will not be required. Salinity Salinity, Total Dissolved Solids (TDS) is an issue in the Colorado River Basin which warrants some discussion. RATIONALE - Page 6 Permit No: COG -070000 Reporting Requirements The results of sample monitoring shall be reported once each year to the Division as discussed in Part I C (4) of the permit. Should the effluent contain concentrations of any parameter in excess of permit limitations, the permittee shall aotify the Division within 5 days of becoming aware of the situation. The permittee shall immediately notify the Division of the occurrence of any discharge or spill not covered by the conditions of the permit. Permit Duration The permit shall not exceed five years in duration. Other Conditions The permittee May add or move discharge points under the authority of the general permit so long as the discharge points are associated with the same construction site and go to the same receiving stream. Should the permittee wish to discharge into a different stream, a request for a permit modification will be required. Should the permittee wish to discharge from another construction site, a new application will have to be submitted to the Division. Special Comment Moat construction activities are performed in a reasonably limited area. Certain activities however cover significant areas of land i.e. sewer Line construction, stream rechanneling, etc. Past and present land use can be extremely varied along the route i.e. landfills, old lagoons, etc. and may severely impact the local groundwater quality. Though the discharges are of short duration, volumes can be extremely high and of low quality. Additionally, the Division's experience has been that contractors must begin construction shortly after the contracts have been Let, which in turn Leaves insufficient time for collection of necessary data and permit issuance. Barring poor quality groundwater, these activities Eit we.LL into this general permit category. ROY ROMER Governor PATRICIA A.
