The San Diego City Council has passed a construction and demolition (C&D) debris diversion ordinance in an effort to extend the life of the city's Miramar Landfill, and to help the city meet state recycling mandates. The ordinance, expected to go into effect next summer, will require applicants for building and demolition permits to pay a deposit based on a project's square footage. After showing documentation of proper materials recycling, contractors can get a whole or partial refund. The city's Environmental Service Department said most of the 400,000 tons of C&D materials accepted each year at the landfill are recyclable. The city currently diverts only 45% of total waste from the landfill.
Water standards book published
The American Public Health Association, American Water Works Association, and Water Environment Federation have released the 21st edition of the Standard Methods for the Examination of Water and Waste-water. Previous editions have served as the definitive water quality testing guide since 1905. The centennial edition provides more than 400 separate methods of water quality measurements used by scientists, analysts, and engineers, including 104 revised methods, 23 new methods, and 16 EPA-approved methods. Physical and aggregate properties, metals, inorganic nonmetallic constituents, aggregate organic constituents, individual organic compounds, radioactivity, toxicity, microbiological examination, and biological examination also are covered.

Wastewater treatment earns award
Little Rock, Ark.-based ThermoEnergy Corp. has received a 2005 Municipal and Industrial Wastewater Treatment Technology Innovation of the Year Award from Frost & Sullivan, a New York City consulting firm. The award recognizes the company's ammonia recovery process (ARP) and ThermoFuel process for contributions to the industry in terms of adoption, change, and competitive posture. ARP is an adsorption process that removes and recovers ammonia from a variety of waste streams. ThermoFuel is a renewable energy process that converts waste-activated sludge into a low-moisture, high-energy fuel that meets exceptional quality Class A standards and can be used to create power onsite or as a low-cost energy resource.
Guide outlines work-zone rules
The Federal Highway Administration has published a guide to help work zone practitioners implement the recently updated work zone safety and mobility rule. Implementing the Rule on Work Zone Safety and Mobility provides a general overview of the work zone safety rule, including its goals and expected benefits. It also includes an overview of differences between the updated rule and the former rule, as well as examples, tools, and resources to help agencies implement rule provisions. The first of four guides intended to support implementation of the rule, this publication contains three technical guidance documents covering specific aspects: public information and outreach strategies, transportation management plans for work zones, and work-zone impact assessment.

EPA to develop drinking water database
The EPA's Office of Research and Development is funding a five-year, $2 million research project—led by environmental consultants Malcolm Pirnie Inc., White Plains, N.Y.—to develop a comprehensive drinking water treatability database. It will house information regarding the effectiveness of nearly 30 treatment technologies for the removal of up to 250 regulated and emerging contaminants. This project answers water utilities' need for a single source of information on available technologies to make use of the best and most cost-effective tools to ensure regulatory compliance. The database is expected to be released to the public by mid-2007.
Guide on protecting wastewater
The National Association of Clean Water Agencies (NACWA) has released the latest document in its series of publications focusing on the protection of wastewater infrastructure assets. Planning for Decontamination Wastewater: A Guide for Utilities explores the potential impacts of wastewater generated during the response to—and cleanup of—a chemical, biological, or radiological terrorist attack. The guide was developed by NACWA under a cooperative agreement with the EPA in an effort to increase the level of awareness within the wastewater community and provide guidance on how to ensure that wastewater infrastructure is protected in the event of an attack.
