The National Biosolids Partnership (NBP)will host a “no charge” webcast – Implementing the New Sewage Sludge Incineration MACT Standard – Issues and Challenges Ahead – on Thursday, April 21 from 2:00-4:00 pm EDT to discuss issues associated with EPA’s final rulemaking to regulate sewage sludge incinerators (SSIs) under the more stringent maximum achievable control technology (MACT) requirements under Section 129 of the Clean Air Act. Some of the topics that will be covered include: background to the regulations, comparison of the proposed and final rulemaking, technology impacts, and next steps.

EPA published in the March 21 Federal Register a final rule that identifies which non-hazardous secondary materials, when used as fuels or ingredients in combustion units, are solid wastes under the Resource Conservation and Recovery Act (RCRA). This RCRA solid waste definition will determine whether a combustion unit is required to meet the emissions standards for solid waste incineration units issued under section 129 of the Clean Air Act (CAA) or the emissions standards for commercial, industrial, and institutional boilers issued under section 112 of the CAA. In this action, This final rule is effective on May 20, 2011.

EPA also issued in the March 21 Federal Register final rulemaking for new stationary sources and emission guidelines for existing sewage sludge incineration units To determine that materials are non-hazardous secondary materials when burned under this rule, materials must not have been discarded and must be legitimately used as a fuel. EPA determined that biosolids were considered as material that is discarded in sewage sludge incinerators (SSIs), and thus a solid waste, prompting the Section 129 CAA rulemaking.  This final rule sets limits for nine pollutants under section 129 of the Clean Air Act: cadmium, carbon monoxide, hydrogen chloride, lead, mercury, nitrogen oxides, particulate matter, polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans, and sulfur dioxide. This final rule is also effective on May 20, 2011.

On March 22, to commemorate World Water Day 2011, Secretary of State Hillary Clinton and World Bank Group President Robert Zoellick signed an agreement committing the U.S. government and the bank to fighting the effects of poor sanitation and trying to ensure safe drinking water in developing countries. The memorandum of understanding directs the resources of 17 U.S. agencies and the bank to addressing water scarcity and water quality, managing water resources, and reducing risks from floods, climate change, and drought. During the World Bank meeting attended by representatives of the United Nations and South Africa, U.S. officials, and bank employees, Clinton noted that access to water has reached crisis levels across the globe and affects not only health, farmers, economies, and climate but political matters as well. The 17 U.S. agencies involved in the agreement are the departments of Commerce, Energy, Interior, State and Treasury, Environmental Protection Agency, Export-Import Bank, International Boundary and Water Commission, U.S. Section, Millennium Challenge Corporation, NASA, National Oceanic and Atmospheric Administration, Overseas Private Investment Corporation, USAID, U.S. Geological Survey, and U.S. Trade and Development Agency.

In 2010, Zoellick said, the World Bank provided $5.7 billion in water financing, $40.8 million in knowledge and technical assistance through its water and sanitation program, and $754 million in guarantees for water investments through its Multilateral Investment Guarantee Agency (MIGA).The Bank’s International Finance Corp. has provided $1.4 billion in water financing to private corporations since 2003 and provided advisory services on public-private partnerships for bulk water, distribution, wastewater management, and irrigation.

Harry Seah, Director, PUB, Singapore

In an interview with Water & Wastes Digest, Harry Seah of the Public Utilities Board of Singapore describes the challenges of creating enough fresh water for the island nation.

Mr. Seah is one of the Opening Session speakers on April 13th at the CWEA Annual Conference in Ontario. The conference theme is “One Water. One World.” Sessions will cover a wide range of topics including wastewater collection systems, treatment, reuse, stormwater and more.

Digest: What is NEWater? What role does it play in the water supply?

Seah: NEWater is the pillar of Singapore’s water diversification strategy. NEWater is ultra-clean, high-grade reclaimed water produced from treated used water.

NEWater has passed more than 65,000 scientific tests and exceeds the Environmental Public Health and U.S. Environmental Protection Agency drinking water standards, as well as the drinking water guidelines established by the World Health Organization.

Introduced in 2003, NEWater is primarily supplied to non-domestic sectors, such as wafer fabrication parks, industrial estates and commercial buildings for industrial and air-cooling purposes. A small percentage of NEWater is also mixed with raw reservoir water before being treated at the waterworks for the drinking water supply.

The Stockholm International Water Institute (SIWI) has announced Stephen R. Carpenter, Professor of Zoology and Limnology at the University of Wisconsin-Madison, USA, will receive the 2011 Stockholm Water Prize. Professor Carpenter’s groundbreaking research has shown how lake ecosystems are affected by surrounding landscape and human activities according to SIWI. Read more at
