San Luis Obispo County Biosolids Ordinance Extended
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.

CASA Requests Publication of Opinion in City of Los Angeles v. County of Kern
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 While this represented a significant victory for CASA, the opinion was unpublished.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.

Compost Giveaway Program
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.

Pyrethroid Registration Review
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.
