What Does EPA Certification Mean for Your Marine Tanks?
Horizon Manufacturing Group’s certification is issued under Section 213 of the Clean Air Act and regulated by 40 CFR Parts 90, 1045, and 1060. These EPA rules govern evaporative emissions from marine and nonroad fuel system components.
Our certification verifies that:
- Horizon’s rotomolded marine fuel tanks meet EPA permeation and vapor-control standards.
- All tanks conform in material respects to EPA-approved design specifications.
- Products are produced under controlled, auditable manufacturing processes.
- Horizon supports ongoing EPA compliance and inspection requirements.
For OEMs and boat builders, this means fewer compliance risks, smoother approvals, and fuel systems ready for regulated markets.
