Measure
The County will require U.S. Environmental Protection Agency (EPA)-rated Tier 4 final diesel engines or cleaner electric-powered, hybrid, or alternatively fueled construction equipment in new construction projects, unless the applicant can reasonably demonstrate that specific equipment is infeasible or regional supply unavailable. If infeasible or unavailable, the contractor will demonstrate how the proposed equipment will achieve similar GHG emissions to Tier 4 final engines, which will be verified by SMAQMD.
Contractors who demonstrate that they meet CARB’s Off-Road Diesel Regulations as a small fleet can qualify for a waiver from this requirement. The County will partner with SMAQMD to provide contractors designated as small fleets information on applicable incentives or grants for equipment upgrades.
Project applicants will include Tier 4 final engines or cleaner electric-powered, hybrid, or alternatively fueled construction equipment in construction lists prior to receiving work authorization for valid grading permits or improvement plans.
