DFARS 252.223-7006 Prohibition on Storage, Treatment, and Disposal of Toxic or Hazardous Materials

Does the regulation require it to flow down?

Yes

Basic, paragraph (c) (in Alternate I it's (d)): 'include the substance of this clause, including this paragraph (c), in all subcontracts that require, may require, or permit a subcontractor access to a DoD installation, at any subcontract tier'. In Alt I, flowing the clause down does not relieve the prime's responsibility to the government.

What it makes you produce

One item for your checklist.

  1. Nothing to send, ever

    There is no paperwork here. It is a rule you follow while you perform the work.

    • Nothing to send — the clause bars storing, treating or disposing of toxic or hazardous material not owned by DoD on a DoD installation

      DFARS 252.223-7006(b)

When it is used

Goes into contracts whose performance gives (or may give) the contractor access to a DoD installation. Statutory basis: 10 U.S.C. 2692 — prohibited to store, treat, or dispose of non-DoD toxic/hazardous material on a military installation, absent a statutory exception or authorization from the Secretary of Defense. Flows down into all subcontracts that require, may require, or permit sub access to a DoD installation, at any tier.

Read closely

No paragraph asks for a submission. The prohibition comes from 10 U.S.C. 2692 and gives way only to a statutory exception or the Secretary of Defense's authorization, and where it does the Government may charge for the service on a reimbursable basis. (a) reads storage as non-transitory holding, which leaves out the temporary accumulation of a limited quantity of material used in or generated by authorized servicing, maintenance or repair.

Alternates

  • Alt I · SEP 2014

    DFARS 223.7106(b) — a Secretary-level exception determination under 223.7104(a)(10) exists.

    Alternate I adds a paragraph (c) putting all financial and environmental responsibility for treatment or disposal authorized under the exception its own text cites as DFARS 223.7104 (10), and 10 U.S.C. 2692(b)(10), on the contractor, and pushes the flow-down paragraph down to (d). It moves liability and paragraph letters, and like the basic clause it asks for nothing to be sent.

Source: acquisition.gov, DFARS 252.223-7006. CODIFIED REGIME, read 2026-08-11 on the part-252 page at DFARS Change 5/7/2026: "As prescribed in 223.7106 and 223.7106(a), use the following clause:" with designation (SEP 2014). RFO CLASS DEVIATION 2026-O0018 (DFARS part 223, effective February 1, 2026) CARRIES THIS CLAUSE AT THE SAME NUMBER: the memo prescribes it at 223.7106 and 223.7106(a) and prints it (SEP 2014). Alternate I is prescribed at 223.7106 and 223.7106(b) in both regimes. So the two regimes AGREE here on number, prescription and designation, and an agreement read is recorded because the alternative is silence that a reader cannot tell from an unread deviation.

This is research, not legal advice. It states what the regulation says about this clause and cites the paragraph behind it. It does not rule on your order, and it does not rule on whether a prime's markings are correct.
