TechKnowServ Corporation (TKS) is strategically located to serve New York, New Jersey, Ohio Pennsylvania, and West Virginia owners and operators of aboveground storage tanks (AST) used to store chemical bulk and petroleum bulk products. In addition to our strategic location, we are proficient in the different jurisdictional requirements for each state. This article outlines some of the aboveground storage tank testing guidelines for each state and provides links to the important documentation that should be reviewed prior to any tank testing to API-650: Welded Tanks for Oil Storage, API-653: Tank Inspection, Repair, Alteration, and Reconstruction, and STI-001: Standard for the Inspection of Aboveground Storage Tanks.

Review of Above Ground Storage Tank Testing Requirements
The requirements for aboveground storage tank testing are largely driven by state environmental laws and regulations. While states generally defer to API-653 and/or STI-001, each state’s regulations must be fully understood by the tank inspection company to ensure that all local regulations are satisfied. Some important tank testing considerations for each state are provided below.

Storage Tank Testing in New York State
Tank testing requirements in New York State (NYS) are outlined in New York Codes, Rules and Regulations (NYCRR). The specific documents are:
6 NYCRR Part 598: Chemical Bulk Storage (CBS) Handling and Storage of Hazardous Substances – Section 598.7 Aboveground tank systems – inspection, and,
2. 6 NYCRR Part 613: Petroleum Bulk Storage – Section 613-4.3 Inspections and leak detection
The NYS CBS regulations require that tank testing be performed on an annual basis. This is largely a visual inspection to identify major tank issues that may require follow-up non-destructive testing. This tank testing includes non-destructive testing (NDT), visually inspecting for cracks, areas of wear, corrosion, poor maintenance and operating practices, excessive settlement of structures, separation or swelling of tank insulation, malfunctioning equipment, safety interlocks, safety trip
