Emission Reduction Credits (ERC's)
Mendocino County is an Attainment Area for all Federal Standards and
Emissions Reduction Credits are NOT required for new large sources.

non-vehicular sources of air contaminants. The Authority to Construct is
issued before construction begins. The Permit to Operate

When Do I Need An Air Quality
State and federal law require permits for any operation or equipment that
has the potential to emit, reduce, control, or eliminate the emissions of
air contaminants. Permits are required:

All new or modified industrial plants, equipment,
processes or operations
Commercial uses, such as dry cleaners, gasoline
stations, auto body shops.
Major indirect sources of air pollution (large
commercial or residential developments)
Large non-agricultural grading operations.
Activities which release air toxics into the atmosphere
Why Do I Need An Air Quality
The District issues permits to ensure that all equipment and processes
comply with federal, state, and District rules. Before any activity which
may release air pollutants occurs, the operator must obtain a permit from
the District (California Health and Safety Code, Section 42300 et seq.)
Issuing permits allows the District to work with businesses to ensure that
their operations comply with applicable state, federal and District rules
and allows the district to identify possible problems before they impact
the public and/or the operation of a business.

The District charges permit fees to cover the costs of reviewing
applications, issuing permits and ensuring compliance. Different fees
apply to different types of permits and equipment. These fees are
Application Fee: This fee is based on the number, types, and sizes
or capacities of proposed equipment. It covers the cost of technical
review of the application, the post-construction inspection and issuance
of a Permit to Operate. For complex projects the fees may be increased to
cover the additional time necessary to evaluate the application, issue the
permit, and the cost of outside contractors. The District sends out a bill
for each application upon completion of the initial review.
Annual Permit Fee: This fee is based on the type of equipment,
complexity and size of the facility’s operation. For most businesses,
permits are reviewed every year, and modified as necessary. A facility’s
annual permit fee is determined from adopted fee schedules. This fee
covers the permit review and compliance inspections.
Permit holders who don’t submit requested information or pay the annual
renewal fee will have their Permits to Operate revoked. Operating without
a permit is a violation of District rules and state law, and involves
