How to Notify Customers of a Noncommunity PWS of a Nonacute Coliform Violation

Step-by-step instructions for notifying customers of a nonacute violation of the MCL for coliform. Links to templates for preparing mandatory language as well as to related forms.

These instructions apply to you if you own or operate a noncommunity public water system—for example, the water system at a camp, prison, school, or similar facility. To notify customers of a nonacute violation of the maximum contaminant level (MCL) for coliform, you must:

  1. Notify customers within 30 days of when we notify you of the MCL violation. [Title 30 Texas Administrative Code (30 TAC) Paragraph 290.122(b)(2)]
  2. Use the mandatory language. [30 TAC Subsections 290.122(b)&(d)]
  3. Issue the notice in at least one of these ways [30 TAC Subparagraphs 290.122(b)(2)(B)&(C)]:
    • by hand delivery
      –or–
    • by continuously posting the notice in conspicuous places within the area served by the system until we tell you that you may take it down [30 TAC Subparagraph 290.122(b)(3)(B)]
  4. Within 10 days of when you issue this notice, send a copy of the actual notice and the signed Certificate of Delivery of Public Notice to Customersto us by mail at:
    TCEQ
    Drinking Water Quality Team Public Notice Coordinator MC-155
    PO Box 13087
    Austin TX 78711-3087
    or by fax to 512/239-3666 [30 TAC Subsection 290.122(f)].
  5. When you have corrected the violation, issue another notice in the same way you issued the original notice. [30 TAC Paragraph 290.122(b)(4)] Then, as described in Step 4, complete Certificate of Delivery of Public Notice to Customers and submit it to us with a copy of this notice.

If you have any questions about these instructions, e-mail us at pdws@tceq.texas.gov or call 512/239-4691 and ask to speak with a “coliform” or “Bac-T” expert in our Public Drinking Water Section.
