The Regulatory Environment
The United States Environmental Protection Agency (EPA) Spill Prevention Control and Countermeasure (SPCC) Rule, 40CFR112, requires in Section 40CFR112.8(c)(6) that tank owners must "Test each aboveground container (tank) for integrity on a regular schedule ..." and "You must combine visual inspection with another testing technique such as ... ultrasonic testing ... or another system of non-destructive shell testing."

The EPA requires all tank owners to perform tank integrity inspections by way of "accepted industry standards", namely the Steel Tank Institute's SP001 (5th Edition) Standard and the API-653 Standard created by the American Petroleum Institute (API). Briefly, all shop-built and field erected steel tanks having 0 to 50,000 gallons storage capacity are addressed by SP001, while tanks larger than 50,000 gallons capacity are addressed by API-653. We perform the SP001 Standard, which applies to tanks that store flammable / combustible liquids at atmospheric pressure with a specific gravity less than 1.0.

The type and frequency of tank inspection (ie, periodic vs certified) is directly attributable to the TANK CLASSIFICATION. Before any tank inspection project is initiated, we determine (at no charge) whether your tanks are Category 1, 2 or 3, to avoid wasting our time and your money on needless inspection work. Sometimes these FREE initial consulations have determined that the prospective tank inspection job was UNNECESSARY!

The STI SP001 Standard is specifically referenced in the SPCC Rule for integrity testing. When an SPCC Plan's professional engineer (PE) references SP001 for tank integrity testing, as per 40CFR112.8(c)(6), s/he knows that their client (tank owner) will be in conformance with the EPA, by employing an "accepted industry standard."

How We Can Help
Our certified SP001 tank inspectors were certified in 2003 and our highly experienced ultrasonic thickness testing (UTT) professionals have as much as 30 years experience performing UTT on myriad tank types in a variety of industrial settings! Our UTT inspection team has Level 2 and Level 3 rated UTT inspectors who take UT readings along historically weak areas (ie, manway and other attachment welds and plate-to-plate welds) and ALWAYS at/along areas having suspected corrosion (ie, paint holidays and/or rust spots). UTT inspections may be performed by the Tank Inspector but we consider this a bad idea, unless s/he has considerable experience performing such work, given that TANK WALL THICKNESS is the predominant factor regarding a tank being certified as Suitable for Continued Service. Given that tank certification rests primarily upon tank wall thickness, all identified significantly thin areas will cause a tank to not become certified until adequate repairs and/or replacement of the isolated material has occurred.

We'll help you STAY IN COMPLIANCE with the EPA's Spill Rule, by inspecting your facility and preparing an SPCC Plan. As needed, our SP001 certified inspectors and UTT professionals will perform tank inspections mandated by Section 40CFR112.8(c)(6) of the Plan. Our certified SP001 tank inspectors strictly follow all elements of the SP001 protocol and provide inspection reports with detailed findings and cost-effective recommendations for keeping your tanks in compliance with the EPA.

IN CLOSING - If you do have concerns that maybe your facility's tanks are not EPA-compliant and thus susceptible to an unannounced EPA investigation (and possible fines), contact us by email or phone (info at bottom of this page). We'll gladly perform a proper inspection of your qualified tanks (see MYTHS below) and provide you with a thorough analysis and appropriate action plan (see MYTHS below), to assure that your fuel and oil storage tanks are in compliance with the EPA.

Tank Inspection MYTHS

While helping our SPCC clients (petroleum marketers, metal recyclers, truck stops and others) stay in compliance with the EPA, we've run across several COMPLETE FALSEHOODS attributable to inaccurate misrepresentations made by one of our competitors!

The following MYTHS that have arisen from this sad situation are DEBUNKED below.

Tank Certification requires vent and ancillary structural repairs - NOT!
When a tank has sufficient shell (wall and roof) thicknesses, coupled with an absence of MIC and significant structural damage, it will likely be certified as Suitable for Continued Service, as per Section 10.0 of the SP001 Standard. By the way - SP001 inspection firms (like us) who don’t provide tank repair services are NOT tempted to recommend potentially unnecessary vent and ancillary equipment repairs.

Tank Certification is contingent upon completion of all non-wall repairs - NOT!
If a tank lacks adequate venting or other tank-related systems BUT nonetheless has adequate tank wall thicknesses (see UTT above) and satisifies the other elements of Section 10.0 in the SP001 Standard, it will likely be certied as Suitable for Continued Service. Do NOT let a tank inspection, tank lining, tank repair firm tell you otherwise,as they're inadvertently or intentionally scaring you into hiring them to "turnkey" the job, when in reality you could get your tanks SP001 Certified and take your sweet time getting the vents and other non Section 10.0 items taken care of as your budget allows.

SP001 tank inspectors can inspect (and CERTIFY) riveted tanks - NOT!
Only API-653 certified tank inspectors can perform inspections on RIVETED tanks!
Beware of tank inspectors who claim "environmental equivalence" via less-rigorous, "self-invented" protocols, as they're more than likely woefully DEFICIENT!

Category 1 tanks under 5,001 gallons capacity require inspection by a certified Tank Inspector - NOT!
Have a qualified tank inspection firm, certified SP001 Tank Inspector or qualified engineer make a determination as to what Category (1, 2 or 3) your tanks fall under and THEN shop for qualified, ethical tank inspectors.

The SP001 Tank Inspector doesn't have to personally inspect each and every tank - NOT!
EACH TANK MUST BE PERSONALLY INSPECTED by the certified SP001 Tank Inspector. Anything else invalidates the tank inspection / certification!

Liners can be used to repair tank walls, to satisfy SP001 Section 10.0 - NOT!
According to the Steel Tank Institute, tank liners do NOT constitute an “adequate repair”, as tank wall integrity is based STRICTLY upon the thickness of the steel wall itself and NOT upon liner coatings or similar tank treatments!
