Questions & Answers / Clarifications

This document provides responses to vendor questions regarding the solicitation for an Oil Water Separator (OWS) system at Mountain Home AFB. It clarifies technical requirements, site conditions, and administrative aspects of the project.

• Hydrocarbon Removal Threshold: The 20-micron threshold is based on the effective limit of fixed media coalescers, driven by observed oil presence downstream of the facility impacting the wastewater treatment plant. Evaluation will include review of calculations, not just "stated" values.
• OWS Design Acceptance: The government is open to various designs that meet requirements, including coalescing plate technology alone, provided separation efficiency is validated through engineering calculations.
• Testing Requirements: EPA Method 1664 testing is not strictly required for commissioning; flow rate and visual/sensor-based validation are acceptable. The government requires verification that the OWS is functioning correctly, accepting other recognized test methods.
• Influent Characteristics: Expected hydrocarbon is Jet A fuel, with unknown concentrations and varying temperatures. Emulsified hydrocarbons are not the primary concern; the focus is on capturing free oil and mechanical emulsions.
• Warranty: The 1-year "no-limit" warranty covers construction work and latent defects, excluding consumables and normal wear and tear. OEM replacement parts are expected.
• Page Limit: The technical proposal page limit will be increased to 50 pages.
• UFC Governing Document: UFC 3-240-01 will govern OWS design requirements, superseding UFC 3-240-04A.
• Environmental Permits: No new NPDES permit is anticipated, and no additional coordination with EPA or Idaho DEQ is expected beyond existing requirements.

Several sections of the SOW will be revised based on these clarifications, including those related to vapor-phase carbon adsorption, explosion-proof venting, and potentially ambiguous warranty language. The clarification on influent characteristics and removal thresholds may impact vendor proposed solutions and cost estimates. The page limit increase for the technical proposal provides more flexibility for bidders.
