SacMetro AQMD Rule 201 requires any business or person to obtain an Authority to Construct and Permit to Operate before installing or operating new equipment or processes that may release or control air pollutants to ensure that all SacMetro AQMD rules and regulations are considered. Following this requirement will enable business owners to make any required design changes early in the planning stage and stay in compliance. Failure to do so may result in civil or criminal penalties, as well as lost time and money in design and/or the purchase of equipment that can't be permitted. We highly recommend you contact the SacMetro AQMD before purchasing or installing any new equipment.
Permits to Operate can be cancelled or corrected by submitting a Permit Cancellation/Correction request form.
Permits to Operate can be transferred to a new owner by submitting a Change of Ownership application and the appropriate filing fee. The filing fee will be equivalent to the permit renewal fee of the previous permit. Please contact the SacMetro AQMD for the appropriate fee. A new permit, with a different permit number, will be issued to the new owner.
Coating and printing operations will also need to submit one or more of the forms below as applicable:
Authorities to Construct cannot be transferred from one owner to another. If there is a change of ownership and an Authority to Construct has not been converted to a Permit to Operate, the Authority to Construct will be cancelled and a new application will need to be filed by the new owner.
When a company changes name but not ownership, the permit holder must request to have their Permits to Operate changed to the new name by submitting a Change of Name request form and the appropriate fee as per Section 307.2 of Rule 301.
For general permit applications (for equipment not listed in the section below), use Form G100 along with all pertinent data (see Form G101 and List and Criteria). If the process will emit toxics, Form HRA100 must also be included. The application must be submitted with the appropriate filing fee in accordance with Rule 301.
