Overview
If you provide remediation, abatement, hazardous material handling, or environmental compliance services on federal sites and installations, your contracts, work plans, schedules, sampling reports, and base access paperwork are Federal Contract Information. That triggers FAR 52.204-21 and a CMMC Level 1 self-assessment with an annual SPRS affirmation.
Environmental work is usually Level 1. CUI enters only in narrow cases: sensitive site information, security related environmental details, and critical infrastructure data that the agency marks. Most remediation and abatement work never sees marked CUI.
Environmental contractors run project management and document systems, field laptops and tablets, and an email tenant. Level 1 covers the systems that hold FCI: email and files for work plans and reports, the field and office devices, and controlled paperwork on site.
Typical contracts you'll see
- Remediation and abatement task orders on federal sites
- Environmental compliance and monitoring contracts
- Hazardous material handling and disposal contracts
- Subcontracts under an environmental or construction prime
- Set aside environmental contracts (8(a), HUBZone, SDVOSB)
What FCI actually looks like for you
Anything below is Federal Contract Information and triggers FAR 52.204-21. None of it is CUI on its own.
Common pitfalls in this industry
- Running project email through personal accounts, which fails FAR 52.204-21 (b)(1)(i) and (iii).
- Using shared field laptops with one login, which fails (b)(1)(i) and (ii).
- Leaving access rosters and reports unsecured in the field office, which works against (b)(1)(viii).
- Letting subs use the owner's credentials to reach the company tenant.
- Assuming field work is out of scope. The FCI in the work plans and reports is what triggers CMMC.
- Treating a sensitive site project as Level 1 when the information is marked CUI.
Your Level 1 action plan
- 01Inventory the contracts: which agency or prime, any -7012 flow-down, any marked CUI. Most environmental work has none.
- 02Move project email and document sharing onto a paid Microsoft 365 or Google Workspace tenant with MFA enforced.
- 03Give field and office staff named accounts and lock down the field and office devices.
- 04Pick one cloud folder for work plans, reports, and schedules, and restrict access to the team.
- 05Secure access rosters and reports in the field office, and keep a visitor log on site.
- 06Write a short boundary description naming the systems that hold project FCI and who can access them.
- 07Run the 15 practice self-assessment, then have a senior official affirm the score in SPRS and re-affirm annually.

Frequently asked questions
Q.We do site remediation for a federal agency. Do we need CMMC?
Yes, once you hold a federal contract or subcontract. The contracts, work plans, schedules, and field reports are Federal Contract Information, and FAR 52.204-21 applies to the systems that hold them. The 15 practices apply to the laptops and email you run the project from, not to the field equipment.
Q.Could environmental work be Level 2?
In narrow cases. If the site information, security details, or critical infrastructure data are marked CUI under DFARS 252.204-7012, that project is Level 2 and needs a controlled boundary. Most remediation and abatement work is Level 1.
Q.Does the prime cover us as an environmental sub?
No. CMMC flows down. If you receive FCI from the prime, you have your own FAR 52.204-21 obligation and need your own SPRS affirmation. The prime cannot affirm for you.
Q.Do I need an SSP at Level 1?
No. Level 1 does not require a System Security Plan under 32 CFR Part 170. You need evidence the 15 practices are met for the systems that hold FCI, plus a short boundary description and a current list of authorized users.
