Case study - Neutralization basin odor control for agricultural chemical production
Challenge: An agricultural plant located in the Midwest manufactures herbicides, pesticides, fungicides, and insecticides. Strict environmental regulations require the company to capture and neutralize all surface runoff and grey water produced at the plant before disposing into the municipal system. In addition, air permits prohibit any odors to cross their fence lines. As the water collects ...

New Air Permitting Requirements Finalized for Class I Areas
Issued in December 2000, the Federal Land Managers' Air Quality Related Values Work Group (FLAG) Phase I report set new visibility requirements and adjusted air dispersion modeling values, presenting new challenges for facilities near Class I areas. The report resulted from an interagency work group comprised of U.S. Fish and Wildlife Service, National Parks Service, and United States Department ...

Major NSR - Planning for Success
In last month’s 4 The Record, Roy Rakiewicz reminded us of the angst created for Environmental Managers by the major New Source Review (NSR) air permitting rules. Roy talked about how changes at existing major air sources could qualify as major modifications under the NSR rules that include both the Non-Attainment NSR (NNSR) and the Prevention of Significant Deterioration (PSD) ...

Air - Multi-Stage Mist Collector for Zinc Strip Rolling Mill Upgrade - Case Study
Challenge A zinc strip rolling mill was having repeated issues with its existing fume/mist collection system - short filter life and frequent maintenance events - which added up to too much $$ being spent. The plant wanted new equipment to be designed to fit within the footprint of an existing platform and connect to the existing duct work with minimal modifications - without cutting corners on ...

Significance of a CALPUFF Near-Field Analysis
Historically CALPUFF air dispersion modeling has been a useful tool for determining ambient concentrations, regional haze, and deposition in Class I areas for Prevention of Significant Deterioration (PSD) applications. Until recently, CALPUFF has not been utilized by minor sources for small permitting projects or for near- field regulatory analyses due to the costs encountered from the complexity ...

Mist and Fume Collector for Zinc Strip Rolling Mill Upgrade
A zinc strip rolling mill was having repeated issues with its existing fume/mist collection system - short filter life and frequent maintenance events. Plant engineers turned to Monroe Environmental to evaluate their needs and recommend a replacement for their outdated, time-consuming, and expensive system. Monroe Environmental engineered and furnished a replacement Multi-Stage Mist Collector ...

EH&S compliance leading the pack, or sitting back?
The rule of thumb is to either comply with the myriad laws, rules, and permit conditions, or face the consequences negative public image, hefty fines, or even jail time. The introduction of the Title V federal air permit rules and the Sarbanes–Oxley Act launched U.S. business into a new era of compliance. Today, companies must have capable systems to monitor processes and emissions on a ...

SMART Containers vs. Silos: Four Advantages
Tall, vertical silos are the go-to technology for storing large volumes of material. However, they aren’t the best solution for every application, and recent innovations in competing technologies make the alternatives worth considering. Horizontal silos—SMART Containers from Biomass Engineering & Equipment in specific—offer advantages over traditional silos. We’ve ...

Not So Fast - Getting That Air Permit Won`t Be As Easy As You Think
Most of the air regulations promulgated by U.S. EPA are developed and implemented to achieve compliance with the National Ambient Air Quality Standards (NAAQS). The NAAQS represent ambient air concentration levels that are established by U.S. EPA to ensure that the general public and sensitive subgroups of the general public are not adversely affected by air pollution. The various NAAQS ...

`Air Permitting for a New Coal-Fired Power Plant,` published in Power magazine, November
Prevention Of Significant Deterioration (PSD) Construction of any new source, including a greenfield power plant, is subject to New Source Review (NSR). If the source is located in an attainment area, it will also trigger Prevention of Significant Deterioration (PSD) permitting, as required by the Clean Air Act (CAA) for major stationary sources of air pollution in attainment areas. A major ...

The Oxidizer Permit Protection Myth - White Paper
It is often assumed an air pollution control permit is enough to maintain emission compliance. Unfortunately, that's not the case. EPA is more aggresssively pursuing air pollution control system failures creating millions of dollars in penalities and fines for organizations. Are you ...

Molycorp`s Mountain pass mine
Location: Mountain Pass, CA Project Completed: 2011 Element Markets was exclusively retained by Molycorp to procure Emissions Reduction Credits (ERCs) for a large expansion of a mining operation in California. At the time there was a shortage of available credits in the area, so we had to think outside the local air basin. We solved the challenge by purchasing credits in an adjacent air district ...
