Submit Your Annual Throughput Reports

For every Permit to Operate (PTO), facilities are required to submit an annual throughput form that identifies the level of production for that permitted process. This information is compiled by the District to quantify actual emissions from each of the permitted sources, and then the District develops an emissions inventory which is reported annually to the California Air Resources Board.

The District doesn’t mail Throughput Forms. Instead, they are provided electronically. The forms have been emailed to each facility’s responsible contact and are also available by clicking the link FIND YOUR FORM below.

Click the link INSTRUCTIONS for guidance on completing the Throughput Forms. The forms are due by March 31, 2024. Please note electronic or digital signatures are accepted.

Permit holders who fail to submit the requested information may have their PTOs revoked. Operating without a permit is a violation of District rules and state law and involves serious penalties.

Please submit your throughput report(s) by e-mail to the District at throughput@ysaqmd.org (best option) or via mail or fax (530-757-3670).

If you have questions, need assistance, or would like the District to send you a blank Throughput Report form specific to your permit(s), please send an e-mail request with your permit number(s) to throughput@ysaqmd.org.

If you need to speak with someone, please call the District at (530) 757-3650.

Yolo-Solano AQMD Reissues Air Quality Warning through September 24, 2023

Yolo-Solano AQMD Issues Air Quality Warning

This Air Quality Warning is in effect through Thursday, September 24, 2023.

The Air Quality Warning for Yolo and northeastern Solano County was reissued today by the Yolo-Solano Air Quality Management District (YSAQMD) and the Yolo County Health and Human Services Agency to notify residents of air quality conditions in the District. Smoke from multiple wildfires burning in northern California and Oregon is impacting air quality through the region. Current air quality levels are UNHEALTHY FOR SENSITIVE GROUPS in many parts of the District, including the cities of Davis, Dixon, Vacaville, Winters and Woodland.

Wind patterns persist, with north winds pushing significant smoke plumes down into the Bay Area and delta breezes creating a wraparound effect, pushing the accumulated smoke into the valley. Transport smoke has increased levels of particulate matter, which is a concern for residents health. Currently, the smoke event is forecasted to last through at least Sunday as weather is expected to change near the active fires.

“Air quality may be changing in a number of our communities, even those far away from the fires,” said Yolo County’s Deputy Public Health Officer Dr. Mary Ann Limbos. “When the air quality is at unhealthy levels, residents should limit their exposure to smoke by reducing outdoor activity and staying indoors if possible. Those most at risk include young children, the elderly, pregnant persons, and people with pre-existing lung or heart conditions.”

If you see or smell smoke, you are breathing it. To reduce your exposure to wildfire smoke:

Check air quality at fire.airnow.gov
Stay indoors with windows and doors closed
Limit or stop outdoor activity, especially exercise
Do not run fans that bring smoky air inside – swamp cooler, whole house fan
Run your air conditioner. If available, use the “re-circulate” or “recycle” setting
Do not smoke, vacuum, fry food, burn candles or do other things that will create indoor air pollution
If you need to venture outside, make sure to wear a well-fitting, high-quality mask such as an N95, KN95, or KF94. Surgical masks do not provide sufficient protection against wildfire smoke.
Use an air purifier with a HEPA filter

The Yolo-Solano AQMD is the air pollution control authority for Yolo County and the northeast portion of Solano County including Vacaville, Dixon and Rio Vista.

(DAVIS, CA) – Today, Yolo-Solano Air Quality Management District (YSAQMD) and the Yolo County Health and Human Services Agency are issuing an Air Quality Warning for Yolo and northeastern Solano County to notify residents of air quality conditions in the District. Transport smoke from multiple wildfires burning in northern California and Oregon is impacting air quality through the region. Current air quality levels are UNHEALTHY FOR SENSITIVE GROUPS in many parts of the District, including the cities of Davis, Dixon, Vacaville, Winters and Woodland.

Winds throughout the day are pushing offshore smoke inland, causing hazy skies and increased levels of particulate matter, which is an air quality concern for residents. This smoke event is forecasted to last throughout Thursday and possibly longer. If you see or smell smoke in the air, you are breathing it. Everyone should take precautions to limit their exposure to smoke and soot, especially children, older adults, pregnant women and people who have heart or lung issue.

“Breathing smoke can irritate eyes and lungs, and can aggravate serious health conditions such as asthma and heart and lung problems,” said Yolo County’s Deputy Public Health Officer Dr. Mary Ann Limbos. “You may notice symptoms like coughing and headaches, and even trouble breathing. In addition to limiting outdoor activity and staying indoors, if possible, check-in on others who may be more susceptible to the health impacts of wildfire smoke. Seek immediate medical care if someone is experiencing chest pain, chest tightness, or shortness of breath.”

To reduce your exposure to wildfire smoke:

Check air quality at fire.airnow.gov
Stay indoors with windows and doors closed
Limit or stop outdoor activity, especially exercise
Do not run fans that bring smoky air inside – swamp cooler, whole house fan

Funding for all other types of organizations, including landscaping businesses, public agencies, and nonprofits, is limited. Once these funds have been expended, applications will still be accepted and will be prioritized in the order that they are received in case additional funds become available. Funding is provided through the Carl Moyer Program.

The Program will provide vouchers to qualifying Applicants for the purchase of cordless, zero-emission lawn and garden equipment from eligible dealers and manufacturers, which are listed below. The District is currently implementing this program for commercial lawn and garden equipment replacement projects only.

Spare The Air Begins May 1st

Each year from May through October, the air districts across the Sacramento region (Sacramento Metro, El Dorado, Feather River, and Placer) join Yolo-Solano to help reduce the production of ozone through the Spare The Air program.

Northern California summers are full of hot and sunny days, which produce greater quantities of ground-level ozone or “smog.” When ozone pollution is high, even healthy people can experience negative impacts. The Spare The Air program encourages residents to drive less, and take actions to help reduce the production of ozone.

Temporary symptoms may include irritation of the eyes, nose or throat, coughing, chest tightness or breathing difficulties during exercise or outdoor activities.

On days when the Air Quality Index (AQI) is regionally forecast to reach 126 or higher, a Spare The Air alert is issued. When an alert is issued, residents can do their part by:
• Walking or riding a bike for short trips, especially in the morning when ozone pollution is at its lowest.
• Taking public transit – it’s easy on the air and the wallet.
• Sharing a ride with a co-worker or friend.

Learn more tips to do your part at www.sparetheair.com.

For every Permit to Operate (PTO), facilities are required to submit an annual throughput form that identifies the level of production for that permitted process. The District has traditionally mailed these forms every January with a due date of March 31. This information is compiled by the District to quantify actual emissions from each of the permitted sources, and then the District develops an emissions inventory which is reported annually to the California Air Resources Board.

This year, the District is not mailing the 2022 Throughput Forms, they are being provided electronically. The forms have been emailed to each facility’s responsible contact, and are also available by clicking the link below.
