MEMORANDUM FOR R E C O R D

FROM: 21 CONS/PKB

SUBJECT: Response to Questions for Solicitation FA251724Q0091, PFAS Wastewater Treatment

1. Below are the questions (Q) and the Government’s responses (A) to the inquiries received between 29

August 2024 to 04 September 2024, at 10:00 AM (MT) as a result of solicitation FA251724Q0091, for

PFAS Wastewater Treatment.

Q1: In order to increase competition for this environmental remediation services contract, would the Government consider applying the NAICS size standard exception of 1,000 employees that also falls under 562910? We are a small business with a PFAS destruction system but cannot qualify to bid under the $25M size standard.

A1: Thank you for your inquiry regarding the application of the NAICS size standard exception for the upcoming remediation services contract. We appreciate your interest in increasing competition.

After consideration, we regret to inform you that we cannot apply the NAICS size standard exception of 1,000 employees for this contract. According to the guidelines for NAICS code 562910 – Environmental Remediation Services, the size standard exception is not applicable in this context for the following reasons:

Government Procurement Classification: For a government contract to be classified as Environmental Remediation Services, its main goal must be to restore or support the restoration of a contaminated environment (not applicable to this acquisition). The contract must involve activities from three or more different industries with separate NAICS codes or smaller sub-components of NAICS codes with distinct size standards (not applicable to this acquisition). If any activity in the contract can be identified with a separate NAICS code and that activity accounts for 50% or more of the contract’s value, the size standard for that specific industry applies, not the Environmental Remediation Service size standard.

Given these criteria, the $25M size standard for NAICS code 562910 remains applicable for this contract. We understand that this may limit your ability to bid, but it is essential to ensure adherence to the established guidelines.

Q2: What is the source of the water to be treated?

• Should I expect oil/grease, high TSS etc. This determines the extent of pretreatment required for my treatment system.

A2: The wastewater to be treated comes from various sources along the flightline.

Most of it, I believe is wash water from aircraft & hanger cleaning and maintenance operations. Also, historical AFFF release discharges have made it in there, so the composition is made up of various chemicals and byproducts.Q3: Is a water analysis available?

• Presumably there’s been prior testing to determine that the water contains PFAS compounds, having an idea of PFAS levels help me determine the most cost-effective removal media choice.

A3: See attachment 5 - B210 UST Sample Results, is the last analysis that was performed on the wastewater.

Q4: How is the determination of feasibility for discharge to sanitary sewer or stormwater system to be made? Is that a site decision or contractor decision? Can you provide info showing locations of the underground storage tank, location for treatment system, and potential discharge points?

A4: Our objective is to treat in-place and discharge to CSU. We are in discussions with CSU to determine the feasibility of that discharge, but as a backup we may redirect the discharge to our stormwater outfall to Pond 3. The discharge to the stormwater system will have to meet the base’s MS4 effluent discharge permit requirements. The goal is to reduce liability of off base transport and prevent any offsite treatment and its byproducts to end up in the municipal landfills.

Q5: Previous contract number.

A5: Contract FA251721P0086

Q6: What is the estimated or contracted quantity of PFAS contaminated wastewater?

A6: Please refer to PWS Para 3.1

Q7: The synopsis initially states that the contract will be awarded to Offeror that represents the Best Value for the Government but in the Basis for Award, states the contract will be awarded to Offeror that represents the lowest price technically acceptable (LPTA). Will the Government use Best Value or LPTA?

A7: To clarify, the LPTA process falls under the Best Value continuum. In this case, the Government will use the LPTA approach, which is a specific method within the Best Value framework. This means that while the Government is seeking the best value, it will do so by selecting the proposal that meets the minimum technical requirements at the lowest price.

Q8: The PWS Introduction/Background requires that the PFAS wastewater be treated onsite and discharged into the Colorado Springs Utilities Sanitary Sewer System. Would off-site treatment and/or destruction be considered technically acceptable?

A8: Only if CSU does not provide PSFB a discharge waiver to the Sanitary Sewer (based on contractor treatment performance) or treatment/destruction process can not meet the base’s effluent discharge permit requirements. Please add to bid transport cost as an alternative option.

Q9: Please provide the analytical profile for the PFAS concentrated wastewater.

A9: See attachment 5 - B210 UST Sample Results

Q10: Please provide the discharge requirements for the Colorado Springs Utilities Sanitary Sewer System.

A10: See attachment 6 – Discharge Request Form CSU, for typical pollutants but PFAS discharge requirements are presently under review.

Q11: Who is responsible for any discharge fees required by the Colorado Springs Utilities?

A11: All testing and analytics for discharge will be the responsibility of the contractor.

Q12: In the PWS, 3.1 Removal and Post-Treatment Discharge, the fifth bullet implies that once the wastewater is treated and concentrated, the PFAS concentrate will be placed in 55-gallon drums that will be disposed of through PSFB HazWaste Program. Please confirm that the disposal of the PFAS concentrate is NOT the responsibility of the Offeror.

A12: The 21 CES/CEIE PSFB HazWaste Manager will coordinate disposal of the drums.

Q13: May we respectfully request an extension to the proposal due date 2 weeks after receipt of government’s response to questions?

A13: Solicitation will be extended to 16 September 2024 at 10:00a.m MT.

Q14: "Any waste products produced, gathered or collected from the treatment or destruction process will be safely transferred to (provided or supplied) 55-gal drums. The used/filled drums will be disposed of through the Installation’s HazWaste Program." Can you please provide this?

A14: Only post treatment byproducts and remaining sludge, sediment, organic matter, etc. left in the tank will be transferred to 55-gal drums provided by the Gov’t.

Q15: "All treated water will meet or exceed disposal requirements a) meets or exceeds CDPHE PFAS Policy 20-1, and intent of EPA 40 CFR 122." This policy reflects testing methods 533 and 537.1. Can you please confirm what testing methods to adhere to?

A15: The EPA Method 537.1 will be required.

Q16: Also, the Offerer is to provide VOC/SVOC/metal/etc... data as per IWS PWS Para 3.1, however there is no indication as to the levels needed to hit for proper discharge permit disposal. Can you please confirm?

A16: See attachment 6 – Discharge Request Form CSU, for typical pollutants and CSU to determine additional limits/level of discharge.

Q17: Can you please clarify the costing sheet as it pertains to the units for testing and mobilization?

A17: Required testing for PFAS and other contaminants IAW EPA methods to determine if water meets the discharge criteria for PFAS and other contaminants in the water. Historically, it has taken up to 8 sampling events to determine if the process is operating correctly and meets all discharge criteria. Mobilization, if can occur in one, that is fine.

Q18: Provide analytical results for the PFAS-impacted water within the UST to include PFAS constituents and concentrations of each constituent. Please include background chemistry to include pH, TSS, and iron content.

A18: Refer to A3.

Q19: What are the acceptable effluent permit levels for discharge to the sanitary/stormwater system, including any constituents of concern outside of

PFAS?

A19: For PFAS, all constituents to non-detectable, for other requires to meet Colorado Springs Utilities standards of meeting new Drinking Water MCL Std is the target and other discharge requirements per their wastewater effluent criteria.

Q20: Are there any restrictions on the discharge flow rate to the sanitary or stormwater system?

A20: No

Q21: Confirm the base will coordinate and pay for any required discharge permitting, including supplying a flowmeter and any volumetric disposal charges.

A21: The installation will not coordinate and pay for any required discharge permitting, including supplying a flowmeter and any volumetric disposal charges, see Industrial Pretreatment (csu.org) for costs and permitting requirements. Please include costs for those activities.

Q22: Provide the size of the laydown area available for the treatment system including the distance from the UST and to the potential discharge manhole (sanitary or stormwater). Or an aerial figure depicting these.

A22: See attachment 7 – B210 UST location.

Q23: Confirm the base will provide drums and transport them from the treatment system laydown area to the base's hazardous waste storage area for disposal by the base.

A23: Installation will provide drums, but Contractor will be responsible to transport to central accumulation point.

Q24: Will the Government provide a one-week extension so answers to questions can be received and incorporated into contractor proposals?

A24: Refer to A13.

Q25: Can all 100,000 gallons of PFAS concentrated wastewater be treated at the same time?

A25: Yes

Q26: What is the source of the industrial wastewater?

A26: Mostly aircraft wash water and maintenance wash water, previous AFFF releases. The tank receives water from Bldgs. 140, 133, 121, 119, 216, 214, 210, and

208. Other industrial processes take place in the facility.

Q27: What are the Current Concentrations of PFAS in wastewater? Are there any sediments at the bottom or oils at the top?

A27: Refer to A3. Anticipated oils/solvents and biological (dead animals) and potential heavy metals in sludge.

Q28: What other contaminants and at what concentrations are present in the wastewater?

A28: Solvents, Petroleum/oils, and biological, unknown levels

Q29: Per Section 3 of the PWS “hazardous contaminants to be safely and https://www.csu.org/Pages/IndustrialPretreatment.aspx permanently destroyed” would using treatment media (examples include carbon and ion exchange) be acceptable for treating the wastewater? If yes, would contractor be responsible for disposal of generated residuals? Or will only destructive treatment technologies be acceptable?

A29: No, based upon knowledge, GAC systems will fail due to the biological present, ION exchange just transfers from one medium to another. Only destructive treatment reduces amount of waste considerably.

Q30: Currently there are no State or Federal regulations for PFAS in wastewater.

What concentrations/standards for PFAS need to be reached in order for the wastewater to be considered PFAS free and be accepted by sanitary sewer? Does the base have an industrial wastewater pretreatment permit?

A30: Colorado Springs Utilities determines the levels to be considered, below detection limits based upon current available testing. Base does not have a pre-treatment permit.

Q31: Per Section 3 of the PWS, will the disposal of any treatment media (i.e., waste products) that will be disposed of through the Installations HazWaste Program be at no cost to the contractor or does the contractor need to cost transport and disposal of treatment media?

A31: The PWS is written to coordinate and transfer to Central Accumulation Point and Gov’t will dispose of waste.

Q32: Per Section 3 of the PWS, If remediated wastewater cannot be discharged to the sanitary sewer or stormwater system and needs to be trucked offsite is the cost for the trucking the responsibility of the contractor or is the contractor only responsible for transferring it into the tankers?

A32: The responsibility of the Contractor.

Q33: The Price Sheet lists “item No. 4 Systems Needs Assessment” and references PWS Section 3.1 but no “System Needs Assessment” is listed in PWS Section 3.1.

Please clarify what the “system needs assessment” is?

A33: The needs assessment describes to the Gov’t what the total technology to be used to treat the contaminated water, not just for PFAS, but also other contaminants (i.e. oils, solvents, Bac-T, etc.). Basically, a description/diagram of the system and what each section treats for. Does require current analytics to determine if proposed system will work.

Q34: The Price Sheet lists Mobilization as 4 units in the Price Sheet and references PWS Section 3.1 but the PWS does not specify what is to be included in the Mobilization task nor why 4 units and not just one unit are requested. Can the government please provide details for costing the mobilization task?

A34: The contractor can bid up to four mobilizations, basically, consider first round of testing to determine the treatability and determine if additional technology is required, plus mobilization for treatment, and any additional the contractor may require. However, since this is a performance based contract ultimately it is up to the contractor to decide.

Q35: Will existing documents and data containing water quality and analytical results for the UST contents be provided?

A35: Refer to A3.

Q36: Will the Contractor have access to a dedicated on-base staging/laydown area for conducting treatment and storage of treated wastewater?

A36: Refer to A22.

Q37: Other than analytical results/reports, will any other technical documentation, reports or deliverables be required?

A37: All available Government reports are attached, and all Contractor reports are listed in the

PWS.

Q38: What level of regulatory review/approval will be required before treated wastewater can be discharged to the sanitary sewer or stormwater system?

A38: Refer to A15.
