Clean Air Act Attorney — Glendale & Los Angeles
A Clean Air Act matter is any dispute or compliance question over air emissions under the federal Clean Air Act (42 U.S.C. § 7401 et seq.) and the California rules that carry it out. DiJulio Law Group advises Glendale and Los Angeles businesses on South Coast AQMD permits, CARB rules, and enforcement.
Who enforces the Clean Air Act against a business in Los Angeles County?
Usually the South Coast Air Quality Management District. Under California law, local and regional air districts have primary responsibility for controlling air pollution from sources other than motor vehicles, while the California Air Resources Board is responsible for vehicles and adopts fuels and other statewide measures. U.S. EPA retains federal enforcement authority under Clean Air Act § 113, and private parties may sue under § 304 after giving 60 days' notice. See how agency enforcement is handled.
How Air Quality Law Reaches a California Facility
The Clean Air Act sets national air quality standards and leaves much of the work of meeting them to the states through state implementation plans. In California that work is split. The Health and Safety Code (opens in a new tab) gives local and regional air districts primary responsibility for sources other than vehicles, and the California Air Resources Board handles mobile sources, fuels, and statewide rules. For most businesses in Glendale and Los Angeles, the agency that matters day to day is the South Coast Air Quality Management District.
South Coast AQMD regulates through permits and source-specific rules. Equipment that emits or controls air contaminants generally needs a permit to construct before installation and a permit to operate afterward, and each permit carries conditions on throughput, control equipment, monitoring, and recordkeeping. Larger facilities that qualify as major sources also need a federal Title V operating permit, which the District issues under its own Title V regulation. Most citations trace back to a permit condition or a recordkeeping requirement rather than to a measured exceedance.
This page covers air-specific permitting, enforcement, and litigation. For the broader overview of emissions, discharge, and hazardous waste obligations, see air, water, and hazardous waste compliance. For responding to a notice already in hand from any agency, see environmental enforcement and compliance. Water discharge questions are covered on the Clean Water Act matters page, and all of these sit within the firm's environmental law practice.
Air issues also surface in deals. A buyer of an industrial property or an operating business inherits permits that may not transfer cleanly, equipment that may never have been permitted, and open notices. Those questions belong in legal due diligence before closing, not after.
What happens after a South Coast AQMD notice of violation?
A notice of violation is the District's formal notice that it has found a violation of a rule, permit condition, or state law. It may lead to a penalty settlement with the District or, if the matter does not resolve, a civil action. Health and Safety Code section 42403 lists the circumstances weighed in setting any penalty.
South Coast AQMD describes a notice of violation (opens in a new tab) as meaning a business is operating in violation of the law, and it treats each day or part of a day a violation continues as a separate violation. Correcting the condition quickly, and documenting when, matters. A business that cannot comply right away may petition the Hearing Board for a variance.
Under Health and Safety Code section 42403 (opens in a new tab), the relevant circumstances include those listed below. They are where a response is built, whether the matter is handled through environmental enforcement and compliance counsel or proceeds to enforcement defense.
- The extent of harm caused by the violation.
- The nature and persistence of the violation, and how long it lasted.
- The frequency of past violations and the record of maintenance.
- Any action taken to mitigate the violation, and the financial burden on the business.
Do I need an AQMD permit to construct and operate?
Generally yes, if the equipment may emit air contaminants or is used to control them. South Coast AQMD Rule 201 requires written authorization before building, installing, altering, or replacing that equipment, and Rule 203 requires a written permit to operate before using it. Rule 203 also prohibits operating the equipment contrary to the permit's conditions.
An air permit also does not travel with the business. Under South Coast AQMD Rule 209 (opens in a new tab), a permit is not transferable from one location, piece of equipment, or person to another, and it becomes void when the permitted equipment is altered, changes location, or will no longer be operated by the permittee. A name change, or an individual owner or partnership of individuals incorporating, is not treated as a transfer; other transactions require a change of owner or operator under the District's guidelines.
That makes permits a closing item in any business acquisition or industrial property purchase, and a planning item before relocating a line or replacing equipment. Confirming the permit status of each unit during legal due diligence helps a buyer avoid operating equipment whose permit became void at closing.

Air Quality Matters That Reach Our Office
Composite examples drawn from the kinds of matters this practice handles. They illustrate common fact patterns and are not descriptions of specific client cases or predictions of any result.
The Unpermitted Spray Booth
A Los Angeles fabrication shop adds a coating line without a permit to construct. An inspector issues a notice of violation. The work is to get the equipment permitted, document the corrective steps, and resolve the notice without an admission that creates problems elsewhere.
The Missing Records
A Glendale facility runs its equipment within limits but cannot produce the daily usage logs its permit requires. The matter turns on reconstructing records and showing that the lapse was administrative.
The Acquisition With Open Notices
A buyer learns during diligence that the seller's facility has unresolved District notices and equipment listed under the wrong permit holder. The purchase agreement needs to allocate that exposure before closing.
When an Air Quality Issue Needs Counsel
- You received a notice to comply or a notice of violation from South Coast AQMD.
- You are adding, replacing, or relocating equipment that may need a permit.
- A permit application was denied or issued with conditions you cannot meet.
- Your facility may be approaching major source thresholds for Title V.
- You are buying or selling a business or property with permitted equipment. See business law and transactional real estate.
- You received a 60-day notice of intent to sue under the Clean Air Act.
What to Do First
Read the permit conditions
Compare the notice against the actual permit condition or rule cited. Many disputes are about what the condition requires.
Preserve operating records
Usage logs, source tests, maintenance records, and continuous monitoring data are the evidence. Preserve them before anyone cleans up files.
Talk to counsel before responding
What you tell the District may be used later. Contact the firm before you submit a written response.
Clean Air Act Matters — Questions California Clients Ask
What Glendale and Los Angeles businesses ask about air permits, South Coast AQMD enforcement, and Clean Air Act claims.
What is the Clean Air Act?
The Clean Air Act, 42 U.S.C. § 7401 et seq., is the federal law that regulates air emissions from stationary and mobile sources. It sets national ambient air quality standards and relies on states to meet them through state implementation plans. In California, the Air Resources Board and local air districts such as South Coast AQMD adopt and enforce most of the rules that businesses deal with directly.
Does my equipment need a South Coast AQMD permit?
In many cases, yes. South Coast AQMD generally requires a permit to construct before installing equipment that may emit or control air contaminants, and a permit to operate once it is running. District rules exempt certain small or low-emitting equipment. Whether an exemption applies depends on the specific equipment and use, so it is worth confirming before installation rather than after an inspection.
What is a Title V permit?
A Title V permit is a federally enforceable operating permit required for major sources of air pollution under 42 U.S.C. § 7661a. It gathers a facility's air requirements into one document and adds monitoring, deviation reporting, and annual compliance certification. In the South Coast region, the District issues Title V permits under its own regulation. Whether a facility is a major source depends on its potential to emit.
What is the difference between a notice to comply and a notice of violation?
South Coast AQMD generally uses a notice to comply for minor or administrative issues that can be corrected within a set period, and a notice of violation for more significant alleged violations that may lead to penalties. A notice of violation typically starts a settlement process with the District. Both should be answered accurately and on time.
What is the CARB role compared with the air district?
Under California law, the Air Resources Board is responsible for vehicular sources, fuels, and certain statewide measures, while local and regional air districts have primary responsibility for other sources, which in practice means stationary sources such as factories and commercial equipment. A business with trucks, portable engines, and stationary equipment may therefore deal with both CARB and South Coast AQMD on different parts of its operation.
Can a private group sue my business under the Clean Air Act?
Yes. Clean Air Act § 304, 42 U.S.C. § 7604, lets any person sue an alleged violator of an emission standard or limitation. The plaintiff must first give 60 days' notice to U.S. EPA, the state, and the alleged violator. The suit is barred if EPA or the state is already diligently prosecuting a court action to require compliance. The notice period is the time to evaluate the claim.
What is a variance from the Hearing Board?
A variance is temporary permission from an air district hearing board to operate out of compliance with a rule while a facility works toward compliance. California Health and Safety Code § 42350 et seq. governs variances, and the hearing board must make specific findings before granting one. A variance does not excuse past violations, and its conditions are enforceable.
Should an air permit issue come up during a business or property purchase?
It should. Permits are tied to specific equipment and operators, and a change of ownership generally requires action with the District. Buyers should confirm that all equipment is permitted, that the permits match current operations, and that no notices are open. Those findings can then be addressed in the purchase agreement through representations, indemnities, or price.
Local Representation
Glendale and Los Angeles sit within the South Coast Air Basin, so local facilities answer to South Coast AQMD rules as well as CARB and federal requirements. Where an air dispute is part of a broader allocation among owners and operators, environmental mediation is often worth considering.
Talk to an Environmental Attorney
Most air citations turn on a permit condition or a missing record. Send the permit and the notice, and speak directly with an attorney before you respond.
