About this file
This document contains a modified Virginia Pollutant Discharge Elimination System permit and a pre-solicitation notice for an environmental remediation services contract.
The modified VPDES permit corrects a typographical error to the quantification limit for iron at Outfall 019 for the U.S. Army Garrison at Fort Belvoir. The pre-solicitation notice indicates that the U.S. Army Corps of Engineers Baltimore District intends to issue a request for proposal for environmental remediation services at Fort Belvoir, Virginia in July 2019. The services will include environmental compliance, restoration, conservation, pollution prevention and management. The single-award task order contract will have a ceiling of $45 million over a base year and four option years. Offerors must register in SAM to participate. The pre-solicitation provides notice that the solicitation will have a total small business set-aside and identifies the NAICS code and size standard.

Re: Minor Modification of Virginia Pollutant Discharge Elimination System (VPDES) Permit No. VA0092771
U.S. Army Garrison - Fort Belvoir, Fairfax County
Dear Colonel Holbrook:
In response to requests dated March 23, 2017, from Fort Belvoir staff please find enclosed the modified permit for the U.S. Army
Garrison - Fort Belvoir. Pursuant to 9VAC25-151-400, minor modifications of the permit may be made to make corrections to typographical errors. Such minor modifications are not subject to the requirements for development of a draft permit or public review
(9VAC25-31-370).
The following typographical error was corrected with this modification:
Part I.A.18 – Outfall 019: The quantification limit for Iron was corrected as follows:
January 1, 2017 (Issuance) May 8, 2017 (Modification)
Parameter QL Parameter QL
Iron 1.0 µg/L Iron 1.0 mg/L
The above modification does not affect any effluent limitations or monitoring requirements previously established for the above referenced permit. Should you have any questions about the permit, please contact Susan Mackert at (703) 583-3853, or by E-mail at susan.mackert@deq.virginia.gov.
