Questions and Answers Amendment 0009

144. Will the Government please list all permits required for the construction efforts at the various sites or provide a point of contact who can help with which permits are required?

Answer: The contractor is required to be familiar with all Federal and state environmental compliance requirements pertaining to their construction/operations as well as applicable DOD/DA policies and installation plans. POC for coordination is Charles Ruerup, Chief Environmental Sciences Division and can be reached at 928-328-2977. Of course YPG will work with the contractor in developing the environmental compliance plan to ensure that it is consistent with the installation's plans and permits and that the contractor is sharing appropriate compliance information with garrison staff.

144a. Regarding environmental permitting and reporting during the construction and operational phases of the facility, should offers consider the use of the current installation level permits (NPDES, Tier III, etc.) or should this facility be considered as a new / standalone facility requiring separate permits and reporting?

Answer: The contractor is both the owner and operator of the facility, hence is responsible for all data collection, reporting and permitting requirements.

144b. For SWPP development, can the client specify if any TMDL has been established for the receiving water and if so please provide details?

Answer: The installation is not aware of TMDL for receiving water. There is no point source discharge for sewer or storm water on YPG. All discharges are to ephemeral washes.

144c. Are offers expected to include the development of a new SPCC Plan for the facility or amendment of the Post's existing SPCC plan?

Answer: The contractor is both the owner and operator of the facility, hence is responsible for all for all federal and State plans associated with the operation.

144d. Should offers consider the use of inlets and other on-post locations to dispose of liquids from excavation dewatering operations and excavated soils?

Answer: DPW can determine where to dispose of uncontaminated soil. Dewatering should not be required. Concrete washout facilities will not be provided. Contractor must containerize wash water from concrete washout. Wash racks are in place for vehicle washing. DPW can determine if contractor may use existing wash racks. No vehicle washing on dirt is allowed. No dumping of liquid waste besides vehicle wash water is allowed into sewer system. Contaminated soil requires characterization, manifesting, shipment to a permitted landfill, at the contractors’ expense. The YPG landfill is not available for contractor use.

144i. If yes, please clarify as to what type of sampling and parameters will be required to facilitate the use of these on-post disposal mechanisms

Answer: Sampling and parameters are determined once the waste source is known. For test methods refer to EPA SW846 various test methods. Local permitted landfills all have their own requirements for waste characterization. Check with local permitted landfills for characterization requirements.

157. Please confirm JP8 has to be filtered upon receipt and treated as aviation fuel during all bulk operations?
