Change in TCEQ ozone e-mail alerts

On February 27, TCEQ distributed the following email:

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?.

Ozone-related air quality issues remain a high priority for the TCEQ.   We will continue to:

  • provide Texans with the most up-to-date information on environmental issues,
  • operate our extensive ozone monitoring network,
  • publish ozone forecasts and make e-mail or text alerts available, and
  • provide near real-time data on our website.

We appreciate your ongoing interest in air quality and if you have any questions related to these updates, please contact us at [email protected].

Two Final Rules Related to the 2008 Ozone NAAQS Published in the FR on May 21

On May 21 EPA published two final rules related to the 2008 ozone NAAQS in the Federal Register.

The first of the two rules:

  1. establishes the method for classifying ozone areas for the 2008 ozone NAAQS;
  2. establishes the attainment dates for areas in each classification;
  3. bumps up several areas in California to higher classifications; and
  4. revokes the 1997 ozone NAAQS for transportation conformity purposes.

Also, published today was the final rule that designates nonattainment areas for the 2008 ozone NAAQS.

Link to second rule (PDF)

Both final rules are effective on July 20, 2012.  The one-year conformity grace period starts on the effective of the designations.
