You are receiving this e-mail because you are subscribed to the TCEQ’s ozone watch and/or ozone warning e-mail alerts.
In the coming days, the TCEQ will release new updates to the e-mail services and webpages associated with our ozone monitoring program. We are making these updates to streamline available ozone information and ensure scientifically accurate displays of the data.
As a part of this release, you will see the following changes to your ozone e-mail subscriptions:
First, starting March 1, 2013, we will discontinue the Ozone/Air Pollution Warning e-mail service. Individuals seeking this type of email service are encouraged to view EPA’s AirNow webpage and EnviroFlash alert program.
Second, we will convert the current Ozone Watch/Air Pollution Watch e-mail service to a service managed by GovDelivery. This service is used by many other Texas agencies and gives you a single location to sign up for any of the updates the TCEQ makes available. This service also allows you to receive text alerts instead of e-mail if you prefer. You are automatically signed up for the e-mail service using the e-mail address you previously provided. If you would like to sign up, cancel, or change your subscription, please visit https://public.govdelivery.com/accounts/TXTCEQ/subscriber/new?.
