As long term wet weather control plans are developed and implemented in accordance with federal and state requirements, the operations and maintenance manager is often faced with developing an operations and maintenance (O/M) budget with little to no background information. The development of Control Plans include detailed capital costs along with some consideration of the associated O/M requirements and utilize a cost-benefit analyses in the selection of specific control options included within the Plan. Capital costs can be amortized over the life the revenue bond sold to finance the project while revenue for O&M costs is derived directly through the rate structure. Without consideration of the O/M costs associated with each control option, the “least cost” capital alternative may result in a higher overall cost alternative when O&M costs are accounted for. In addition, O/M costs can dramatically impact sewer rates for wet weather control facilities, which must be properly budgeted for. This paper discusses the importance of considering O/M costs in developing a long-term wet weather control plan.

CPI Installs RTO at Tire Manufacturer
Catalytic Products International (CPI) recently completed the installation of a new TRITON Series Regenerative Thermal Oxidizer (RTO) at the Northeast USA location of a global automotive tire manufacturer for the abatement of Volatile Organic Compounds (VOCs). The new 30,000 SCFM TRITON-30.95 Regenerative Thermal Oxidizer (RTO) will control VOC emissions from the rubber mixing operation which includes two (2) existing Banbury Mixers with capacity for an additional mixer to be added in the future. The rubber...
International Tire Recycling Spotlight: Venezuela
Tire recycling is a serious global concern. Scrap tires take up far too much space, they can spawn devastating tire fires that burn for weeks or even months when stored together in large numbers, and they they leach chemicals into soil and groundwater. Recycling is an absolute necessity, but not easily done. Most developed countries have produced millions of scrap tires (at the very least), and many developing country are either already there or well on their way to having a similar massive recycling problem on...
Nuclear Facility Lighting Recommendations and Guidelines
Nuclear Facility Lighting Recommendations and Guidelines Nuclear power plants have very strict lighting requirements due to the delicate nature of work conducted in such facilities. Operators typically avoid experimental or untested luminary designs; and opt for traditional lighting options that have been tried and tested for safety and reliability. This article expounds on the complex requirements of nuclear power plant fixtures and medical cyclotron vaults. The post below also specifies the type of lighting...
Tire Shredding: The Best Alternative
From cars and trucks to planes, tractors, and forklifts, tires are used for a wide variety of vehicles. And those tires don’t last forever. Regardless of how many miles a tire travels, it should not be used longer than ten years past its manufacture date, as the rubber will grow brittle and can crack. This isn’t usually a problem, though, since most tires are replaced within three or four years. In fact, Americans generate nearly 285 million scrap tires per year. So, where do all those old tires...
