Living in Seabrook, you may smell strange odors from time to time. Many of these odors are harmless according to Harris County Pollution Control; however, somethings a strange odor may mean something more. 

Local Emergency Planning Committee

If you smell an odor in your area, please access EHCMA’s CAER Online mobile app first to see if any information is available. This app and the information posted to it is provided by the Local Emergency Planning Committee (LEPC), which comprises the cities of La Porte, Morgan's Point, and Shoreacres. Seabrook borders many of these communities, and while we do not have many chemical plants or refineries in our city, these communities do. 

LEPC works with local governments to develop emergency plans and increase citizen awareness of the appropriate actions to take during a chemical emergency. The LEPC works closely with the cities, schools, and community to encourage emergency preparedness and provide shelter-in-place education to those who live and work in our area. As a part of this effort, the LEPC sponsors and participates in several community outreach events each year.

The emergency preparedness app launched by LEPC is available to anyone who would like more information on local hazards, notification sign-ups, alarm test schedules, damage report forms, evacuation maps, and much more!

Download the app today by searching "EHCMA CAER Online" at the Apple and Google Play stores. If no information is available about the odor on the CAER Online app, please report the odor to Harris County Pollution Control at 713-920-2831.  You may also contact the Seabrook Office of Emergency Management at 281-291-5700 for questions or concerns.
