OES to test soil, groundwater

Oklahoma Environmental Services announced Wednesday the testing of soil and groundwater at 55 petroleum storage tank sites across Oklahoma, including Enid and the surrounding area.

The tank sites, registered as “temporarily out of use,” will be tested for potential leakage. They currently don’t meet Environmental Protection Agency’s guidelines either because of not meeting upgrade requirements for continued use or they have not been permanently closed to EPA standards, according to OES.

Recently, Oklahoma Corporation Commission solicited bids from environmental consultants to conduct the sampling effort to determine if any of the tanks have previously leaked. OES won the bid to perform testing, and will begin at each site by drilling either 5 feet or 20 feet below the surface to collect soil and groundwater samples.

If contamination is found, pending eligibility, an available state fund is open to help with required follow-up actions, according to OES.

In a similar situation in 2015, OES examined a site in Okmulgee formerly known as Catfish George’s Place, where former convenience store owner George LeGrand had tanks on his property needing to be removed, but was worried about it being costly. OES approached LeGrand and helped to resolve the storage tank issue.

“Our commitment is to work as aggressively as possible to resolve cases and secure the environmental safety of the communities we serve,” said OES President Deanna Atkinson. “And getting to represent the best interest of clients like Mr. LeGrand is just icing on the cake.”

OES has offices in Oklahoma City, Tulsa and Enid, and completes field work and remediation with in-house consultants and field technicians.

All 55 site assessments are scheduled for completion by May 15.

Drilling for safety

The Journal Record

Deanna Atkinson’s employees are drilling holes and looking for petroleum, but she doesn’t want to sell oil. The president of Oklahoma Environmental Services and her staff are looking for leaking gasoline tanks. She is one of two contractors tasked with determining if closed fueling stations are seeping petroleum products into the ground.

The Oklahoma Corporation Commission received $150,000 from the U.S. Environmental Protection Agency to assess hundreds of shuttered gasoline stations across the state.

If contractors find pollution, however, it will take more money, time and work to remediate the contamination.

In the 1980s, the EPA strengthened regulations on petroleum storage tanks, requiring leak detection and prevention equipment. Many small business owners didn’t have the money to make the changes, and subsequently closed their businesses. Yet the rules didn’t require them to remove the noncompliant tanks.

The federal program is designed to help identify sites where gasoline or diesel flowed into soil or groundwater. The OCC determined that 1,745 tanks in the Sooner State needed upgrades, but only 1,319 made leak detection and prevention changes. Those out-of-service tanks can stay in the ground as long as monitoring equipment is maintained, said Robyn Strickland, agency Petroleum Storage Tank Division director.

However, 426 tanks were never upgraded or removed, she said. Letters to their operators went unanswered or were returned, so she prioritized sites that didn’t have a responsible party.

“We’re here to protect the environment,” Strickland said. “If we can’t contact the owners, at least we can identify those (sites) with contamination.”

The most recent round of funding covered the cost to assess 37 orphaned sites. A typical site has an average of three tanks, but Strickland didn’t have figures on how many tanks will be addressed with the $150,000 grant. The analysis and assessments must be completed by Sept. 30.

Atkinson won a contract to address 23 sites across the state. Her employees typically drill three 20-foot holes, taking soil and water samples. A laboratory will analyze the results to determine if gasoline or diesel leaked. One soil core appeared to have petroleum, but she hasn’t yet received confirmation.

“In an ideal world, you remove a tank when you quit using it,” Atkinson said. “That is when you do the site assessment to determine if there was a release of the product.”

Removing the pollution is another challenge. If tanks have been leaking for decades, there could be a growing plume of gasoline or diesel underground. The longer the sites are neglected, the harder and more expensive it is to get rid of the contamination, Atkinson said.

Contaminated orphan sites are eligible for federal money from the Leaking Underground Storage Tank Trust Fund. Strickland said she couldn’t estimate how long it would take to remove all the old tanks because remediation efforts depend on federal money.

“It is all contingent on funding and being able to locate someone who is responsible,” Strickland said. “That is the hardest part, is to find someone.”

Investigation of Old Gas Stations Begin

Oklahoma Environmental Services conducts site assessments in an attempt to find contamination

OKC, OK July 08, 2015 – Oklahoma Environmental Services is performing site assessments at twenty-three former fueling facilities in Oklahoma this month. The purpose of the assessments is to determine whether subsurface soil or groundwater contamination exists. The facilities have underground, petroleum storage tank systems that were not upgraded to meet regulatory requirements in the late 1980s. The tank systems remain unused and are registered as “Temporarily Out-of-Use (TOU)” with the state regulatory agency, the Oklahoma Corporation Commission (OCC).

Deanna Atkinson, president of the consulting firm Oklahoma Environmental Services, said, “We are investigating subsurface soil and groundwater at these locations to see if any contamination exists. Ideally, the soil and groundwater would be tested when the tanks are removed. Unfortunately, these tanks are basically orphaned so there are no responsible parties stepping up to remove the tanks. We’re sampling to see if a problem exists. The health concern would be that gasoline or diesel has leaked out of the tanks, into surrounding soil or groundwater. If that is the case, our company will clean it up”. Atkinson cited the reason these sites have not been assessed before now is the lack of a financial mechanism. This recently changed when Oklahoma received a Federal grant for the investigation.

Robyn Strickland, OCC Petroleum Storage Tank Division (PSTD) Director stated they received a grant from the Environmental Protection Agency for sampling these sites. The EPA had money available for state improvement projects so states were able to bid for that money. Strickland said their preference would be to use the money to remove the underground storage tanks but state Indemnity Fund and EPA grant monies will not pay for tank removals, it could only be used for sampling the facilities’ soil and groundwater. Strickland said criteria for candidate sites were those with: returned mail, no response to staff’s notifications and underground tanks that had not been upgraded to current regulatory standards.

Salim Douglah, OCC PSTD Technical Manager, said the goal of sampling is to satisfy pre-closure sampling protocols for when they resolve the issue of how, when and what mechanism to close these TOU tanks. When asked if the pressure would be on the owner to close the tanks, Mr. Southwick, OCC PSTD Legal Counsel, said that is what they are working on. Mr. Southwick said there is a lot to consider such as the interpretation of who is environmentally responsible versus someone who is the owner.

Currently, Oklahoma has approximately 1,700 underground storage tanks that previously stored petroleum products registered as Temporarily Out-of-Use.
