Suite 500 Denver, Colorado 80202 Re: Compliance With Air Quality Laws Dear Ms. Schmittdiel, On behalf of the Aspen/Pitkin Clean Air Advisory Board, I will take this opportunity to reinforce the position of the Board relative to. clean air laws and EPA activities in Aspen. In an informal action of the Board at a regular_ meeting held June 13, 1990, the following was discussed. In your response (dated May 25, 1990) to my letter (dated April 12; 1990) you stated, "The EPA is required to comply with all Federal, State and Local air pollution laws." This being relative to the proposed clean-up of contaminated soils at the Smuggler Mountain Hazardous Waste Site. With that commitment, the Board felt specific laws should be identified for your reference and complied with prior to any actions. The Clean Air Advisory Board expects compliance with the following air pollution laws and subsequent laws that may be promulgated which may replace current applicable statutes, 1)Colorado Air Quality Control_ Regulations and Ambient Air Quality Standards. - -Regulation 1 - Emission Control._ Regulations For Particulates, Smokes, Carbon Monoxide And Sul_f_e_r Oxides For The State Of Colorado -Regulation 3 - Regulation Requiring An Air Contaminant Emission Notice, Emission Permit Fees 2) Pitkin County Code, Title III - Air Pollution Regulations To conclude, the Board also wants to remind you the following documents have been requested, but have not yet been received by various review groups in the community. -Air sampling protocol (including placement of air monitors). The placement of one PM10 monitor ."between the main intrusive activities .and the existing Aspen PM10 monitor", as you stated in your recent letter, does not offer enough definition for the Board to accept. -Health Risk Assessment, which will define action levels of CAAB Request June 14, 1990 Page 2 risk to the community and will state at what level remediation work will be terminated if the public is at risk. -The Citizen Consent Decree --The Potentially Responsible Party Consent Decree -Acceptance of the Institutional Controls by the EPA Thank you for your attention and response to these concerns.

In accordance with the provisions of FAR 16.402-2, an award fee evaluation procedure is hereby established for the determination of the amount of award fee that will be payable under the contract for remediation of the smuggler Mountain mine tailings as described in this solicitation/ specification. Cast -plus -award fee (CPAP) contracting is a cost -reimbursement type contract with special incentive fee provisions which may be changed for each evaluation period. This type of contract consists of two parts: (1) a base fee between 0 and 1 percent of the target cost; and (2) an award fee in addition to the base fee. The base fee will be paid in monthly installments based on the target cost. The maximum amount of award fee is 9 percent of the target cost. This award fee is divided between a cost management award fee of 0-3 percent of the target cost and the Project Management Award fee of 0-6 percent of the target cost. The determination of the cost management award fee and the project management award fee will be evaluated separately. The amount of cost management award fees payable under the contract may range from no fee to the maximum amount stated in the contract. Discussion of the cost management performance will be made for each of the respective award fee periods specified. However, payment of the cost management fee will be determined solely on the final contract cost and paid only after receipt of the final contract invoice. No cost management award fee will be made prior to the final contract invoice receipt. The amount of project management award fee payable under the contract may range from no fee to the maximum amounts stated in the contract for each of the respective award fee periods specified. Award fee periods are based upon the completion of lots. These periods will be: Award Fee Period Lots Completed (Both a and b must be completed) Period #1 a. 35 mobile home lots b. 10 residential lots Period #2 a. 60 mobile home lots b. 25 residential lots Period #3 a. 85 mobile home lots b. 35 residential lots Period #4 a. all mobile home lots b. all residential lots Note: Mobile home lots are within Smuggler Run Mobile Home Park and Smuggler Mobile Home Park. All other lots are classfied as residential lots for this paragraph. As such, each plot plan is considered a lot, although the plan may have more than one property shown on it as in the case of a commons area plot plan for Smuggler Mobile Home. The amount of award fee earned each period shall be determined by the Contracting Officer, whose determination shall not be subject to appeal under the "Disputes" clause of the contract. Each period's award fee shall be determined as objectively as possible by Reclamation based on the contractor's performance, in accordance with the procedures and evaluation criteria set forth in this clause. This assures full contractor management independence in pursuing excellence in performance. H-5 @ H.12 COST REPORTS (a) General. The Contractor shall categorize costs by the 7 remedial units shown on drawing 2 (1556-4-003-15). In addition, the West End Properties shall be divided into 3 subunits. Subunit 1D shall be the area Southwest of Lone Pine Road and Gibson Avenue. Subunit 1C shall be the area Northeast of Lone Pine Road and west of Park Circle. Subunit 1B shall be the remaining area in the West End Properties not identified in the subunits above. Therefore, the contractor shall categorize all costs for the project into the 9 remedial units and subunits described above. (b) Daily Cost Reports. The Contractor shall submit daily cost reports to the Contracting Officer and the designated COIR. The cost reports will contain detailed information on personnel, equipment, materials, general and administrative costs, committed funds and other costs directly associated to the project. The daily cost report shall specify each employee, employee work classification, employee ID, hourly labor rates, total hours, labor cost, labor burden, travel cost, and per diem. The Government will not reimburse the Contractor for a per diem rate greater than the standard Government rate. The report shall identify each equipment item, equipment hours, equipment down time, and equipment rate. Also, identify material costs, materials use, invoice number, and vendors. Copies of the invoices shall be attached to the daily cost report. The daily cost report will include a daily time sheet signed by the Contractor's designated representative. The report will be reviewed by the Site Engineer and the Contractor's designated representative, and corrections or adjustments will be made before both have signed the document. The original daily cost report, signed by the Contractor's authorized representative, and one copy on an IBM compatible disk, either in dBase or Lotus format shall be given to the designated Site Engineer on a daily basis. Copies of applicable invoices shall be attached. (c) Monthly Report.
