Underground/Aboveground Storage Tanks
- Federal Regulations, 40 CFR Part 280/281 (promulgated under the Resources Conservation and Recovery Act) and Minnesota Rules Chapter 7150, mandated that most underground storage tanks (USTs) used to store petroleum had to be upgraded with corrosion protection, overfill and spill prevention, and/or leak detection by December 22, 1998. In order to comply with these requirements, DEHS hired a qualified environmental consultant to conduct a compliance audit of all the University's USTs in 1998: in all, approximately 70 storage tank systems at 50 University locations in Austin, Crookston, Duluth, Morris, Minneapolis, Rosemount, St. Paul and Waseca. The audit showed that most of the tanks were in compliance with the state and federal UST regulations. Approximately 20 tanks were identified as non-compliant, thus DEHS hired qualified environmental consultants and licensed tank contractors to bring the systems into compliance. As of today, all of the University's tanks have been appropriately upgraded, replaced, removed, or taken out of service and to comply with the state and federal UST regulations.
- Federal Regulations, 40 CFR Part 280/281 (promulgated under RCRA) and Minnesota Rules Chapter 7001 and 7151 mandate that most aboveground storage tanks (ASTs) used to store petroleum be upgraded with corrosion protection, overfill and spill prevention, and/or leak detection within the next few years. Most of the University's petroleum ASTs was evaluated as part of the tank audit commissioned by DEHS in 1998 in order to meet the deadlines for UST compliance. The audit showed that most of the tanks were in compliance with all state and federal UST regulations.
- Several ASTs, including the large tanks at the Minneapolis Heating Plant still must be upgraded in the next few years. The Minneapolis Heating Plant ASTs are the responsibility of Foster Wheeler, Inc. which has the contract to operate the University Minneapolis Steam Plant.
- In accordance with Minnesota Rules Chapter 7105, whenever the University has removed an underground storage tank, this task has been completed by a licensed tank contractor and monitored by a qualified environmental consultant. Over the past 5 years, DEHS, often in conjunction with other University departments, has removed dozens of tanks at various locations. Petroleum releases have been detected at several of these sites. These have all been reported and investigated in accordance with Minnesota Statutes Chapter 115 and Minnesota Rules Chapters 103H and 7060. At some sites, some corrective actions consisting of removal and proper off-site disposal (typically by thermal treatment) have also been completed at the direction of DEHS in accordance with these rules. Petrofund reimbursement from the Minnesota Department of Commerce has been obtained by environmental consultants hired by DEHS to help off-set up to 90% of the cost of investigating and cleaning of impacted soil and/or ground water at many of these sites (regulated under Minnesota Statutes Chapter 115C).
- All existing petroleum storage tanks are being disclosed as part of property transfers in accordance with Minnesota Rules 116.48. This task is being completed by DEHS (often in conjunction with the Real Estate Department).
- DEHS is responsible for AST storage of hazardous wastes (regulated under Minnesota Rules Chapter 7001) and agricultural chemicals (regulated under Minnesota Statutes 18B, C, and D).
