# Pro access — screen Connecticut addresses against the tank register

> Check hundreds of Connecticut addresses against 12,749 tank facilities and six DEEP files at once. Prices published.

## Pro access

One address at a time is free and always will be. This page is for the people screening two hundred.

### Who this is for

Environmental consultants running a Phase I Environmental Site Assessment under ASTM E1527 — the search required by the federal All Appropriate Inquiries rule (40 CFR Part 312) before a buyer can claim the landowner liability protections that CERCLA offers; lenders and insurers
screening collateral; property groups triaging a portfolio; tank contractors
looking for the sites still running unprotected steel.

The work that does not scale is the joining. Six files, one identifier, and
a question that crosses all of them — done by hand, for two hundred
addresses, it is a week.

### What we do

- **Your list, resolved.** Send addresses or facility
identifiers; get back the tanks, their construction and dates, and the counts
from all four record files, as a spreadsheet.
- **A watch on a portfolio.** The Department refreshes weekly.
We hold your list and tell you what changed — a new release, a new
action, a tank taken out of use.
- **Direct access** to the same static index this site
searches.

### What it costs

Two things are sold here. The work above is priced on volume. **The
datasets have a published price**:

- **Change feed — USD 300 / month**Or USD 3 000 a year. At every collection, what came in, went out or changed since the previous one. This is the part that does not age.
- **One slice — USD 90 / month**The feed restricted to a single town, for those who do not need the rest.
- **Full snapshot — USD 4 000, once**The state of the register on the day of delivery, every field included. Listed last on purpose : a snapshot ages.

The full field list, the measured fill rates and the order form are on [the datasets page](/data.md).

The pages of this site are free and will stay free : **an official fact belongs to no one**. What is sold here is the compilation work — extracting the Connecticut tank register, reconciling it, dating it, and delivering it in a usable form.

**Not a consumer reporting agency.** This site
and the datasets sold from it are **not** consumer reports under
the Fair Credit Reporting Act, and must not be used to decide anyone's
eligibility for employment, credit, insurance, housing, or any other purpose
covered by the FCRA. If you need a background check, use a screening company
that operates as a consumer reporting agency.

### Tell us the size of the list

How many addresses, how often, and what you need back. We answer every enquiry by hand.

No payment is taken here — an enquiry opens a conversation and an invoice follows. [What we do with this](/privacy.md).
