WERF has initiated a project in which a model would be developed to assist in site specific breakpoints for nitrogen and phosphorus that would be dependent on the receiving water and specific conditions. WERF is requesting assistance to fund the complete project which is on a short timeframe for completion (13 months).
The current project funding is –
CASA is a longtime supporter of the National Biosolids Partnership (NBP). NBP recently released a new report Enabling the Future: Advancing Resource Recovery from Biosolids.
The California Integrated Waste Management Board (CIWMB now CalRecycle) published a guidance document in September 2009 titled “How Anaerobic Digestion Fits Current Board Regulatory Structure”. This was based in large part on an earlier guidance document from December 2007 entitled “How Conversion Technologies Fit Current Board Regulatory Structure”.
On March 12, the San Luis Obispo County Board of Supervisors unanimously approved an extension of the existing interim biosolids ordinance until March 2017 as requested by County staff and supported by CASA. The existing ordinance is far from ideal from CASA’s perspective, but far better than the other options that were under consideration. The Board of Supervisors also evaluated concerting the interim ordinance to a permanent one or funding an environmental impact report ( EIR) for a new permanent ordinance, which is even more restrictive.
On March 12, the California Court of Appeal for the Fifth Appellate District granted the requests of CASA, its co-Plaintiffs and several amici to publish its opinion affirming the preliminary injunction against the Kern County ordinance banning the land application of biosolids (Measure E).

On March 5, 2013 CASA submitted a letter to California Court of Appeal for the Fifth Appellate District requesting publication of the opinion in City of Los Angeles v. County of Kern. In early February, the Court issued an opinion finding in favor of CASA and its co-Plaintiffs and upholding a preliminary injunction preventing Kern County from enforcing Measure E, the initiative ordinance banning the land application of biosolids. While this represented a significant victory for CASA, the opinion was unpublished.
California Court of Appeals Upholds Preliminary Injunction Preventing Enforcement of Measure E, Kern County's Biosolids Ban
On February 13, 2013, the California Court of Appeal for the Fifth Appellate District issued an opinion finding in favor of CASA and its co-Plaintiffs, upholding a preliminary injunction preventing Kern County from enforcing Measure E, the initiative ordinance banning the land application of biosolids. The Court found that land application of biosolids is a major, widespread, comprehensively regulated form of recycling, and that the trial court's decision to grant a preliminary injunction in this case was entirely appropriate.
Please find below a letter sent today to South Coast AQMD opposing their proposed Rule 1110.2 which would set stringent emission limits on stationary internal combustion engines using biogas, effective July 1, 2014.
The San Francisco Public Utilities Commission (SFPUC) has given away biosolids compost twice yearly from 2007 through 2009 at the two wastewater treatment plants in San Francisco. The goal with the program is to increase public awareness about biosolids and expand in-city reuse opportunities, and promote green technology and urban gardening. The program was extremely popular with the public.
- The highly treated, safe, nutrient-rich, organic material derived from the wastewater treatment process that can be, and is, beneficially recycled.
CASA's Biosolids Program was launched in 2003 to provide proactive biosolids industry leadership in the State of California. The mission of the Biosolids Program is to:
CASA has been working for the last year and a half on behalf of Tri-TAC; with BACWA, SCAP, and CVCWA and our consultant Kelly Moran, with the Department of Pesticide Regulation (DPR) and pyrethroid manufacturers on their pyrethroid review. This is the process used by DPR to decide what restrictions or prohibitions need to be placed on pyrethroids. We are also working with US EPA since it is scheduled for similar reviews.
