- CH2M Hill Report: A Recycling Exemption for Oil/Water Separator Wastes at a Large Military Base in California
Enviremedial Services Inc. was awarded the Oil Water Separator Management Services Contract on Marine Corps Camp Pendleton after several demonstrations to high-level military, environmental and contracting officials at the Base showing our unique management service to recycle the effluents from their many oil water separators.
Previous to our contract, the Base used the traditional method of pumping out all the water, oil and sediment from the oil water separators and having 100% of that waste hauled away, oftentimes as hazardous waste. Base officials were impressed with our demonstrations and also impressed that during the first year of our contract OWS, being 87% of total waste removed from the base, was reduced by 97.6%. Annually, we typically save Camp Pendleton up to 99% of the waste from oil water separators that they previously had hauled off their base. As well, our system saves two gallons of water for every gallon we process. In order for the separators to function properly, the dirty water must be removed and the separator refilled with clean water to a minimum of 85% total capacity. Our system cleans the dirty water and returns it to the separator. This not only saves the Base the cost of hauling off the dirty water, but also the cost of refilling the separator with clean, municipal water.
From 1999 to today, Camp Pendleton MCB has saved over 4.7 million gallons of water, with 99.1% waste minimization, versus basic pump and dump services.
ESI currently manages 80 separators on Camp Pendleton. Our pricing structure was developed to ensure savings to the Base over their traditional method of pumping and hauling the waste. By calculating the typical price per pound to haul off the waste, we were able to develop a pricing structure for them that saved them substantial amounts annually. Our management services include complete management of the oil water separators. Through our services, the customerís equipment is inspected and continually remains in top working order.
In order guarantee the base meeting it's OWS budget, ESI evaluates the contract an presents a firm, fixed price for the term of the contract. Our customers agree that it is beneficial to them to have the management services take complete care of their equipment and allow them to know that their prices will be fixed over the life of the contract without surprises to their budget.
On Camp Pendleton, our pricing for servicing the 80 oil water separators has saved the government about 40% over traditional methods.
The personnel at Camp Pendleton have been very satisfied with the services our management contract offers them beyond the traditional method of hauling off waste. If there are any problems with their oil water separators, they can call us directly and those problems are fixed, generally within 24 hours. Each oil water separator is inspected quarterly to determine the need for cleaning. Whether the separator needs to be cleaned once a month or once a year, the personnel at the Base know that the management of the separators is ESIís responsibility. ESI continually receives high ratings from our customers at Camp Pendleton. The Base has also won several Government and environmental awards based on our services.
Our customers at Camp Pendleton, California referred Enviremedial Services, Inc. to the US Army Reserves. After initial contact with USAR personnel, we performed a demonstration of our management services at Camp Pendleton. The USAR personnel we impressed with our level of service and with our waste minimization capabilities.
Enviremedial Services, Inc. was awarded a contract in October 2004 to manage the 37 oil water separator sites controlled by the US Army Reserves. This contract differs from our other on-site customers because the sites are located throughout California, Arizona and Nevada. Rather than have personnel permanently staged on-site, ESI personnel travel site-to-site to manage the separators.
By their own calculations US, Army Reserves saved $180,000 and reduced waste 83% in the first year of their ESI contract.
Because we are not processing and reusing the sediment on-site, ESI personnel containerize and leave the sediment at the facility's 90-day yard. The financial and environmental savings are dramatic in this situation as they are for our on-site customers. For example, with traditional pumping services, USAR was hauling off the entire contents of the OWS by the truckload. With ESI's recycling process, only the minor amounts of sediment are hauled off by the waste contractor. Typically, this is less than 15% of the capacity of the OWS.
While servicing the separators, ESI inspects and makes minor repairs to the unit. Any major repairs needed are reported to the USAR and handled through the usual contracting methods.
ESI provides USAR with advance monthly schedules and contacts each site prior to their arrival. USAR personnel receive monthly reports detailing the disposition of the water, oil, and sediment at each site.
