NSW Underground Petroleum Storage Systems

upss hazardous contamination leak

Underground Petroleum Storage Systems  (or UPSS), are installed in many different locations, from service stations, fuel depots and petroleum refineries to other commercial/industrial premises that may use UPSS such as mine sites, car rental agencies and air ports. Underground Petroleum Storage Systems are great as they optimise the amount of available land, are not susceptible to vehicular collisions or vandalism and create a more aesthetically pleasing area by moving potential eyesores out of sight, but what is out of sight, is often out of mind, leading to neglect and late detection of petroleum leaks.

The issue with leaking underground petroleum storage system’s is that petroleum based products, such as petrol used in your car, contains chemicals such as Benzene (among others) which is toxic to aquatic ecosystems, and considered carcinogenic towards humans. When UPSS leaks occur, these chemicals escape, contaminating the surrounding soil, water aquifers and polluting habitats of not only plants and animals, but humans as well. Once a leak occurs, the owner or person responsible for the UPSS can be fined up to $44,000 and be forced to pay the costs of remediation works which could run into the hundreds of thousands to millions of dollars.

Leaking tank

In response to the dangers of UPSS leaks, the EPA requires operators to regularly check for leaks in fuel tanks and pipes used to store and handle petroleum products as outlined in the “Protection of the Environment (Underground Petroleum Storage Systems) Regulation 2014.“ The UPSS 2014 regulation states that every installation of underground petroleum storage systems, each underground tank must be double walled with a non-corrodible outer wall. All tanks must also have a tank leak monitoring system with overfill protection and loss monitoring procedures in place with the ability to detect a loss of 0.76L per hour (section 4.2), failure to comply, record and report all incidents may result in fines of up to $44,000.

While these measures may seem excessive, the regulation has been designed to detect any potential tank leaks or loss of product early, to minimise contamination and remediation costs which far outweigh the costs of implementing a proper automatic tank gauging system, such as the OMNTEC Proteus series of ATG’s. These advanced automatic tank gauging systems are able to monitor product level, water level and temperature. The Proteus series of ATG also satisfies the EPA requirements by providing an advanced tank leak monitoring system with loss monitoring algorithms that exceed EPA requirements, high level overfill protection and product distinguishing leak monitoring in the interstitial space of your double walled underground tanks.

Semrad’s experience with UPSS has been proven time and time again, as new and old customer’s alike continue to come back for new systems. We have provided advanced automatic tank gauging & leak detection systems to companies like Caltex, PNG Power, and NYRSTAR. Our customers continue to use Semrad instruments as we provide the best service and IECEx certified equipment at competitive prices.

If you have a UPSS installation in need of automatic tank gauging and tank leak monitoring, feel free to give us a call or send through an email, we’d be happy to have a chat and try to help you out!
