METHODOLOGY · UPDATED NOV 2, 2026
How we source and check what this site says
Every rule summary here quotes the rule it summarizes and shows the date it was last checked against the rule text. Every county figure comes from a published TCEQ register or report. Where a fact could not be sourced, the page says so instead of guessing, and when we get something wrong, the correction is logged below.

30 TAC Chapter 285, read from the Texas Administrative Code and TCEQ’s OSSF pages Checked: Each rule page shows its date; Oct 5, 2026

How a page is checked
- Each rule page lists its sources and a “Last verified” date. A rule is quoted where the wording matters, and its citation sits beside the claim.
- Where a rule sets no number, the page says so. North Carolina’s non-renewal notice has no day count in the rule, so none is invented.
- A county’s filing channel is shown at one of three levels: Confirmed with the office, From county pages that the county published, or Not confirmed, in which case the page says so and asks providers who file there to tell us.
- Totals are recomputed from the per-county rows on every build, and automated checks compare them, so a region page, the 2025 report and the county pages cannot disagree.
- The tools never average between published rows. Where the source does not answer a question, the tool says so rather than giving a reading of its own.
- A brand with no retrievable manufacturer manual gets no entry in the alarm guide.
- We do not name or price competitors, and we publish no testimonials.
Corrections
Oct 26, 2026 The county, region and tool sitemaps now carry the date each page’s content last changed, and every county and rule page publishes the same date in its structured data. The county pages had been dated Oct 5, 2026 — the date the dataset was assembled — while their text changed on Oct 17.
Oct 17, 2026 Texas county page summaries corrected. 79 of 254 carried no figures and 62 said “0 licensed MPs based here”; each now states the county’s provider and permit figures and leaves out a zero. Each county page had also repeated its opening paragraph as the answer to its first common question; the questions now have their own answers.
Oct 15, 2026 North Carolina anaerobic drip (Type Vd at or under 1,500 gpd) is inspected on the same schedule as Type Va and Vc: twice a year after a quarterly first year. Pages had said drip was inspected more often; only flows above 1,500 gpd are.
Oct 14, 2026 The correction below was itself wrong, and is reversed. Each maintenance provider license is counted once, under the county of the license holder’s mailing address, so adding the counties up does not count anyone twice. The Texas hub shows the 1,357 licensed providers again. County and region pages now say these are providers based in the county, which is what the figure measures; many also work in neighbouring counties.
Oct 14, 2026 The Texas hub showed a “licensed providers” total that added up each county’s count. A provider licensed in several counties was counted once per county, so the figure overstated the number of providers. It now shows how many counties have at least one licensed provider.
Oct 13, 2026 The Texas county pages now show their common questions on the page, not only in the page’s structured data.
Oct 9, 2026 The Texas 14-day filing deadline is now cited as 30 TAC §285.7(e)(1)(B) everywhere. Six pages, including the home page, the tour and the free-tools hub, cited §285.91, which sets the four-month test frequency.
Oct 9, 2026 North Carolina inspection frequency corrected. A low pressure pipe system (Type IVa) is inspected twice a year from the start; the quarterly first year applies only to advanced pretreatment (Type Va/Vc at or under 1,500 gpd). Pages had said both were quarterly in the first year.
Oct 9, 2026 Removed unsourced tips from the county cheat sheet on the free-tools hub. One said a technician must sign the report; Texas requires the maintenance provider’s signature (30 TAC §285.7(b)(3)).
Oct 5, 2026 Hays, Williamson and Travis counties moved from a stated filing channel to “not confirmed”, because no published source could be found for the channel we had shown.
Nov 1, 2026 Harris County’s report channel is now marked unknown. The maintained county source names an email address for maintenance contracts, but does not establish that inspection reports go to the same mailbox. The page now distinguishes those documents and asks providers to confirm the report channel.
Nov 2, 2026 The product tour now labels its confirmations as illustrative and removes unsourced portal labels for Hays and Williamson. Product pages distinguish researched county channels from enabled automated connectors. North Carolina county badges now use the maintained source status. These presentation corrections do not establish any new verified filing channel.
