Structural Integrity Testing and Inspection

Above Ground Tank Inspection Services

Owners and operators of petroleum-containing aboveground storage tanks (ASTs) may be subject to the Spill Prevention, Control and Countermeasures (SPCC) rule, a regulation mandated by the Environmental Protection Agency (EPA) to prevent the discharge of oil into the environment, and to control spills if they should occur.

Regular inspections are required of facilities with more than 1,320 gallons of total oil storage capacity and must be carried out to applicable industry standards. Avoiding the SPCC requirements and puts your business at risk of lost time of navigating the state and federal EPA bureaucracy, remediation costs and substantial fines. 

Formal inspections of process piping and tanks are also required for the Risk Management Program (RMP), Process Safety Management (PSM) regulations, state and federal hazardous waste storage requirements, tiered permitting, and local fire codes. These requirements are generally outlined in your facility specific plans and procedures and apply to hazardous chemicals or large quantities of waste.

Pacific Engineering & Consulting can help your organization meet all EPA and other regulatory requirements and avoid costly mistakes. Our licensed professionals have performed thousands of inspections for a variety of facilities throughout California to help our clients stay in compliance.

Title 22 Hazardous Waste Tank Assessments

Businesses that are classified as large quantity generators of hazardous waste and are using a tank for storage, are required to have these tanks inspected by a licensed professional engineer every five years. 

The assessment examines the tank and secondary containment tank to ensure it is adequately designed and constructed. The inspector will also examine the tank condition, the materials being used in the tank, the piping, secondary containment, seismic bracing, and more. 

Until recently, local Certified Unified Program Agency (CUPA) inspectors have often overlooked PE tank certification, especially the five-year renewal requirement. However, more CUPA inspectors are beginning to pay close attention to these requirements, so this assessment and certification should not be ignored. 

Pacific Engineering & Consulting can provide these assessments for you, as well as certifications that your tank systems comply with all regulations and requirements. Tank and containment certifications will be provided by a PE licensed and registered with the State of California.

Please contact one of our licensed engineers to learn more about how we can help you with Hazardous Waste Tank Assessments

API-570 Process and Pipeline Inspection Services

The API 570 Piping Inspection Code sets the requirements and guidelines needed to maintain the safety and mechanical integrity of piping systems. While it was primarily intended for those systems in the petroleum and chemical processing industries, this code can be applied to any industry that uses piping systems.


Pacific Engineering & Consulting offers pipeline inspection services including; piping inspection, risk-based piping inspection, pressure testing, and Hydrostatic Testing Witness & Compliance required by California's Office of the State Fire Marshal (OFSM) requirements.

Our certified inspectors can offer a wide variety of tests and evaluations including:

Integrity testing is any means to measure the strength (structural soundness) of a container shell, bottom, and/or floor to contain oil, and may include leak testing to determine whether the container will discharge oil (67 FR 47120, July 17, 2002). The integrity testing and routine inspection requirements apply to aboveground bulk storage containers with a capacity of 5,000 gallons or greater, including Large (field-constructed or field-erected) and small (shop-built) aboveground tanks..
