Clean Air Branch

Mission Statement

At most times and in most places in Hawaii, we enjoy some of the best air quality in the nation. However, we do have air pollution as does any metropolitan area, so the Department of Health (DOH) works diligently to regulate and monitor air pollution sources.

The Clean Air Branch (CAB) is responsible for air pollution control in the state. The primary services of the branch are provided by its three sections: Engineering, Monitoring, and Enforcement. These sections conduct engineering analysis and permitting, perform monitoring and investigations, and enforce the federal and state air pollution control laws and regulations.

The Clean Air Branch is issuing a mandatory No Burn Period for the following areas:

HAWAII ISLAND – Kau District

  • The “NO BURN” is currently in effect until further notice.

Agricultural and conditionally allowed open burning is prohibited while a No Burn Period is in effect unless a waiver is provided by the Director.  

Violation of a No Burn Period may result in both civil and administrative penalties of up to $10,000 per day per violation.

Engineering Section

Reviews air applications and issues air permits of potential air pollution stationery sources. Evaluates, through application of dispersion modeling, the potential impact of an air pollution source on ambient air quality. Evaluates the control technology, operations, and fuels consumed to assess the types and potential air emissions from the various sources. Compiles and maintains a statewide air emissions inventory for the air pollution sources.

Monitoring Section

Monitors the activities of the stationary sources for compliance with the applicable rules and permit conditions. Recommends enforcement action where violations have occurred. Conducts annual inspections of major sources and investigates incidents and complaints. In conjunction with the Air Laboratory, establishes and maintains the ambient air monitoring network and conducts special air monitoring studies as necessary. Compiles, assesses, and manages the data retrieved from the monitoring stations producing applicable graphs and reports.

Enforcement Section

Initiates case development of alleged violations, determines the penalty, drafts and issues the notice of violation, and assists and participates in the conference, hearing, and legal process. Assesses, proposes, or comments on corrective measures, settlement agreements, penalties, and administrative or court actions. Conducts “smoke reading” training classes to provide continuing certification of inspectors in the technique of evaluating visible smoke.
