Rancho Cucamonga, CA – Last week, the Inland Empire Regional Composting Authority (IERCA) reached an impressive milestone by selling three million cubic yards of high-quality compost.
“This is a tremendous achievement for the Inland Empire Regional Composting Authority and all staff involved,” stated IERCA Board Chairman Jon Blickenstaff. “It was especially exciting to see the IERCA founding Chairman, John Anderson, in attendance while the three millionth yard of material was loaded and shipped out to our community where it will be used to create healthy soils to save water.”

The Inland Empire Regional Composting Facility was constructed in 2007 as a joint project of the Inland Empire Utilities Agency (IEUA) and Sanitation Districts of Los Angeles County to provide Seal of Testing Assurance (STA) certified, top quality compost throughout southern California and Nevada.

“As the largest indoor composting facility in the nation, IERCA’s facility in Rancho Cucamonga is completely enclosed to confine byproducts and odors in a controlled environment,” explained Blickenstaff. “The facility produces and sells nutrient rich, weed-free, consistent, and easy to use compost under the SoilPro Product name. SoilPro Products can be used to improve soil structure over time and reduce irrigation frequency by enhancing water retention.”

For comparison, three million cubic yards fills:

  • 42,857 fully loaded semi-trucks
  • 214,288 standard size dump trucks
  • AT&T Stadium (Dallas Cowboys) – 81 times
  • 69,767.44 standard shipping containers
  • A line of semi-trucks reaching from IERCA to Salt Lake City, Utah (approx. 650 miles)
  • A standard football field up to 500 feet in depth of compost

“IERCA has continued to cost-effectively provide and manufacture exceptional quality compost while maintaining an excellent environmental compliance and safety record,” continued Blickenstaff.

The Inland Empire Regional Composting Authority (IERCA) was created as a public entity on February 27, 2002 by a Joint Powers Agreement (JPA) between the Inland Empire Utilities Agency (IEUA) and County Sanitation Districts of LA County (LACSD). This agreement empowered both IEUA and LACSD to acquire, construct, operate and maintain a composting facility. IEUA and LACSD have jointly evaluated composting as an economically and environmentally-sound method of beneficially reusing biosolids that are generated from the wastewater treatment facilities operated by each.
