High Desert Compost Recycling Facility FAQ

Q:   Can you explain the compost recycling process?

A:   At the wastewater treatment facility, biosolids are processed and only those biosolids that meet strict quality standards for pollutants may be composted. The remainder of biosolids are either incinerated or sent to a landfill.

The biosolids that are delivered to the composting facility have been "dewatered" and, while moist, it is not raw sludge. A front loader mixes the biosolids with green waste to quicken the composting process. The mixture is turned regularly to expedite the composting process further and minimize the smell. After 60 days, the mixture has become compost and is trucked to farms and wineries throughout the Inland Empire to be used as fertilizer for their crops and vineyards.

Q:   What are the benefits of compost recycling?

A:   Compost recycling offers multiple benefits:

  • It provides farmers a valuable resource.
    Compost yields far better crops than chemical fertilizer and is less expensive.
  • It is better for the environment.
    Chemical fertilizer has the potential to damage the environment pollute groundwater and, therefore, is much riskier to use than compost.
  • It saves scarce water.
    When used for agriculture or gardening, the compost acts like a sponge, capturing the water and keeping it from filtering through the sandy soil, which means that farmers use less water for their crops.
  • Recycling sustains the earth for a better tomorrow.
    Whether it is aluminum cans, paper or biosolids, it makes more sense to reuse a valuable resource rather than have them take up scarce space in landfills.

Q:   Are there other compost recycling centers in operation?

A:   Yes, they exist in virtually every state in the nation. Some of the larger compost facilities exist in or around such cities as Los Angeles, Denver, Philadelphia, Boston, Seattle, New York, Washington D.C. and Austin, Texas.

Q:   Where will the Nursery Products compost recycling site be located?

A:   The site will be located eight miles west of Hinkley and 22 miles west of Barstow. The nearest point of reference is the former Hawes Auxiliary Airport. The site was selected because it is isolated from residents and businesses and is at a site that will have minimal environmental impacts.

Q:   Will the water supply be safe?

A:   Yes, the project will be constructed to ensure that no flood or storm water flows from the site. The site is located in a different groundwater sub-basin than either Hinkley or Barstow. Further, the groundwater flow from both Hinkley and the Hawes facility is towards Harper Lake, which is north of both.

Q:   How will the storm water control berms be constructed?

A:   A grading plan will be developed for the site which will be reviewed and approved of by the County Department of Public Works. The intention is to have a balanced cut and fill plan so that no soil is imported or exported from the site during construction activities.

The site is designed to the highest storm water design standards, which is the worst rain event that could occur in 100 years. Storm water will be retained on site and allowed to evaporate in retention ponds. Flood waters will be diverted around the facility.

Q:   What will the smell be like at this site and will it reach my neighborhood?

A:   The compost recycling site will have a musty odor that may smell of ammonia, which is one of the key nutrients in fertilizer. With proper operations the smell will be minimized. Nursery Products will not accept food waste, which has a far more pungent smell than compost recycling. The EIR found that there would be no adverse odor impacts from the composting facility.

The closest community to the site is Hinkley, which is eight miles away.

Q:   Will there be flies in my neighborhood?

A:   No, there will not be fly problems at the site. Nursery Products has developed a strict green waste acceptance program. Green waste will be primarily commercial landscaper tree/wood waste. The operating plan will keep the flies to a minimum. Furthermore, because Hinkley is eight miles away, the few flies that may be at the site will not impact any neighborhoods.

Q:   Will the trucks adversely impact traffic in the local community?

A:   No. The traffic to and from the facility will add only 2% to the existing traffic flow. The County’ traffic consultant has found this minor change to be insignificant.

Q:   Where are the biosolid and green waste recyclables coming from?

A:   The Inland Empire. Nursery Products provides recycling services for communities like Barstow, San Bernardino and Lake Arrowhead. The Inland Empire produces 600,000 tons of biosolids per year and the Nursery Products site can accept approximately one third of that total.

Q:   Where will the power come from to run this facility?

A:   The Hawes facility will be environmentally responsible as possible and will rely on solar panels and/or wind power to provide much of its electrical needs including air conditioning, heat, water pump, etc. A generator will be used to supplement renewable energy sources and run some of the equipment used to process the finished compost.

Q:   What kind of regulatory oversight will this project have?

A:   Seven different government regulatory agencies oversee this facility including the

  • U.S. Environmental Protection Agency (EPA) (Metals and Pathogen levels)
  • California Integrated Waste Management Board (CIWMB) (composting operations)
  • California State Water Resources Control Board (SWRCB), Lahontan Region (surface and groundwater)
  • Mojave Desert Air Quality Management District (air quality)
  • San Bernardino County Health Department (vectors, metals, pathogens and composting operations)
  • San Bernardino County Planning Commission (conformity with conditional use permit)
  • Mohave Water Agency (water usage)

Q:   What is an Environmental Impact Report (EIR)?

A:   An Environmental Impact Report (EIR) is a study conducted by the government agency (the County of San Bernardino in this case) with permitting and zoning oversight of the property in question. The EIR analyzes all potential environmental impacts of the project and renders a determination whether they are "less than significant," "significant but mitigatable," or "significant and unmitigatable." The results of the study help provide scientific information to the elected leaders who are charged with determining whether the site should be permitted. The applicant (Nursery Products) was required to deposit the money necessary to fund the EIR so no tax dollars are used.

Q:   How will the site get water?

A:   The property has groundwater pumping rights, although its use of water will be minimal, primarily for dust control. Drinking water will be supplied by bottles. The water pump will be powered by solar panels.

The composting process does not consume any water.

Q:   Will the project have any detrimental affect on the Desert Tortoise?

A:   The EIR specifically analyzed impacts to various local species including the Desert Tortoise. Nursery Products is working with the US Fish and Wildlife Service to ensure the project is designed and operated consistent with their requirements to protect endangered species, such as the Desert Tortoise.

Q:   What are the health-related impacts of the facility?

A:   Commercial compost recycling has occurred in Southern California for the past 81 years and there is no scientific evidence of health-related impacts from the process or the use of composts. The State Water Resources Control Board found that, "To date, no significant outbreaks of infectious disease have been associated with biosolids land application practices." The National Research Council of the National Academy of Sciences found that "there is no documented scientific evidence to indicate that the Part 503 rule (EPA’s Biosolids regulations) has failed to protect human health."

Q:   How does biosolids composting compare to a septic system that many homes have in rural areas?

A:   Most states allow individuals to use septic systems in rural areas. Individual homeowners can treat and dispose of their sewage under their property. The septic system allows water with high nitrates to percolate directly to the groundwater. Biosolids composting releases no liquid streams, either to the groundwater or surface water. The potential for adverse groundwater impacts from too many septic tanks is far greater than biosolids composting.

Q:   When will this compost recycling facility open?

A:   Nursery Products hopes to begin its compost recycling once it receives all of its permits and approvals in late 2008.
