BEANO FOR BOSSIE COULD CLEAR THE AIR.Byline: Joe Florkowski Staff Writer DIAMOND BAR - Increasing composting or changing the diet of dairy animals may be ways to limit the amount of air pollution the dairy herds of the Chino Valley Chino Valley can refer to:
Julia Lester, program supervisor A Program Supervisor is the chief administrator of a school program, such as the high school, elementary school, middle school or pre-school. A Program Supervisor is comparable to a Principal (school), with the responsibility of enrolling students, hiring new teachers, placing for the AQMD AQMD Air Quality Management District AQMD Action Quake Map Depot , said such alternatives could work for dairies that face requirements to sharply reduce emissions from manure manure, term used in the United States to refer to excreta of animals, with or without added bedding; also called barnyard manure. In other countries the term often refers to any material used to fertilize the soil. in the next few years. Manure, particularly from dairy animals, contains high levels of ammonia and volatile organic compounds volatile organic compound Environment Any toxic cabon-based (organic) substance that easily become vapors or gases–eg, solvents–paint thinners, lacquer thinner, degreasers, dry cleaning fluids that contaminate con·tam·i·nate v. 1.

On Wednesday, Tetra Tech Inc., a Pasadena engineering firm, presented a report to an AQMD working group, composed of dairy organizations, owners and private entrepreneurs. The group provides feedback to the district, which is developing rules to limit livestock waste air emissions. The report, based on data from the local regional water quality control board, found that the concentration of dairy animals on farms has risen from an average of about 1,300 animals per dairy in 1997 to about 1,600 animals per dairy in 2000. The Tetra Tech study also found the average amount of manure produced by a dairy animal is somewhere between 2.7 and 3.5 tons a year. Dairy organization members questioned the numbers of animals in the study, given some of the recent farm migrations from the area in recent years. Tetra Tech will take the suggestions presented from the working group and look at other dairy studies in the region, said Charles Egigian-Nichols, a senior manager with the company. Wednesday's study was one of five projects the AQMD is conducting to find methods to limit the emissions of ammonia and volatile organic compounds. The AQMD also intends to research whether compost operations and reducing the amount of liquid in manure can also limit the air emissions. The AQMD plans to introduce rules for livestock waste emissions in 2002 and implement them by 2004, with the goal being to reduce ammonia emissions by 50 percent and VOCs emissions by 27 percent. The new rules will affect dairies in the district's jurisdiction, which includes the Chino Valley. |
