The Usual Suspects - U.S. EPA 2011 - 2013 Enforcement Initiatives
The U.S. Environmental Protection Agency (U.S. EPA) has announced its 2011 through 2013 National Enforcement Initiatives to handle national environmental and public health problems. For air pollution, the initiatives include addressing air pollution from the usual suspects: the largest sources of particulate matter, nitrogen oxides, and sulfur dioxide. This includes continued recent enforcement ...

The Five CISWI Considerations
With so much talk of boilers and heaters since the 4 Rules were published in early 2013, most facilities are focused on developing an understanding and strategy to comply with the Maximum Achievable Control Technology (MACT) standards for Boilers (commonly referred to as Boiler MACT). However, one of the 4 Rules is the Commercial and Industrial Solid Waste Incineration (CISWI) rule, and ...

Flare Gas Measurement Innovation: Retain Flow Metering Accuracy Even if Gas Composition Changes
It’s a fact oil wells almost always produce natural gas along with the petroleum. Nine times out of ten, the excess gas (typically hydrocarbons) is flared off or simply vented as-is during upset conditions in the process. The environmental impacts of “flaring” this excess gas into our atmosphere has resulted in government regulations like 40 CFR Part 60 Subpart OOOO (also known ...

An Introduction to the Topic: Controlling Mercury Emissions from Coal-Fired Power Plants
Untitled Document Mercury is a hazardous air pollutant (HAP) that circulates around the globe for a year before depositing back to earth. Mercury emissions from electric power generation sources were estimated by the U.S. Environmental Protection Agency (EPA) to be 48 t/yr, constituting the single largest anthropogenic source of mercury in the United ...

Modernising gas fired power plant boiler damper drives and damper bearings - Case Study
Sector: Power Generation Category: Fluid Power Actuators, Services Products: PM/DM, Retrofit Overview The challenge of modernising the instrumentation on an old utility boiler can be overwhelming, especially when the boiler was originally commissioned in 1964. Power utility base load preference has historically been the domain of the larger coal fired boilers. That has been the desired ...

U.S. EPA Promulgates Final Air Toxics Standards for Compression Ignition Reciprocating Internal Combustion Engines (RICE)
On March 3, 2010, U.S. EPA promulgated final National Emissions Standards for Hazardous Air Pollutants (NESHAP) for existing compression ignition (CI) stationary Reciprocating Internal Combustion Engines (RICE) that were not previously regulated by the existing, so called, RICE MACT (i.e., 40 CFR Part 63, Subpart ZZZZ). The RICE MACT rule was originally promulgated in 2004. The March 3, 2010 ...

A Case Study in Implementation of the National Emission Standard for Hazardous Air Pollutants for the Portland Cement Industry at a Major Source
The regulations at 40 CFR 63, Subpart LLL are commonly known as PC MACT because the rule establishes the maximum available control technology for hazardous air pollutants (HAPs) from portland cement plants in the United States. There are 188 HAPs specified in Section 112 of the Clean Air Act Amendments of 1990. Two classifications of HAP emitters are specified in 40 CFR 63. Major sources of HAPs ...

Cementing the PC MACT
On September 9, 2010, the U.S. EPA promulgated the final amendments to the National Emissions Standard for Hazardous Air Pollutants from Portland Cement Manufacturing Industry (40 CFR 63 Subpart LLL), also known as the PC MACT. EPA’s self-proclaimed “historic” rulemaking includes some important implications for cement manufacturers and other sources that may be subject to ...

New solid waste definition proposed
When the Boiler MACT rule was vacated in 2007, one key element in the court challenge was that many non-fossil fuel materials burned in industrial boilers should be classified as solid wastes and regulated accordingly. Along with the recently proposed Boiler MACT and rules for commercial/industrial/solid waste incinerators (CISWI), EPA proposed criteria to determine whether non-hazardous ...

The Wait Is Over; The New Boiler MACT Is Here
The Wait Is Over; The New Boiler MACT Is Here April 29, 2010 was a busy day for U.S. EPA and marked the culmination of months and years of background effort and planning related to air toxic emissions from boilers. U.S. EPA has released pre-publication versions of four (4) proposed rules on their website that, when finalized, will impact thousands of facilities. The proposed rules are all ...

Long-term sampling - A method for continuous emission monitoring of dioxins/furans and mercury
Introduction The continuous emission monitoring of the different compounds which are emitted by industrial facilities is an important topic to approve the compliance to different regulations like WID. However, there are several compounds which cannot be measured in real time. Specific dioxins/furans (PCCD/PCDF) and other POPs (Persistent Organic Pollutants) cannot be measured by online monitors. ...

INTO THE VOID...U.S. EPA`s recent boiler MACT and CISWI information collection request
Background - The United States Court of Appeals for the District of Columbia Circuit (court) has been quite busy in the last few years hearing environmental cases, particularly air quality related topics. On June 8, 2007, the court vacated and remanded two (2) U.S. EPA rules promulgated under the Clean Air Act (CAA)-The Commercial and Industrial Solid Waste Incineration (CISWI) definitions rule ...

Shooting a Moving Target - Permitting Fugitive Volatile Organic Compound (VOC) Emissions
Untitled Document ABSTRACT Fugitive emissions from components at chemical processing facilities often appear as allowable emission limits in construction (New Source Review) and operating (Title V) permits issued by state permitting authorities – a subtle contradiction to the federal and state level regulations that regulate those very emissions. Both federal (New ...

Primary Standard Gas Flow Calibration—The Only Guarantee of Accuracy
At Sierra, we have a saying: “An instrument’s accuracy is only as good as its calibration.” The accuracy of your mass flow controller (MFC) is essential in assuring the efficiency, performance, and quality of your flow meter. In many cases, if your instrumentation is not calibrated, then a decline in performance is possible due to sensor drift from the factory calibration. ...

LDAR deficiencies lead to enhanced requirements
Leak detection and repair (LDAR) programs are required as part of the standards established in 40 Code of Federal Regulations (CFR) 60 (NSPS), 40 CFR 61 (NESHAP), 40 CFR 63 (MACT), and 40 CFR 264 (Hazardous Waste Handling). An LDAR program is a facility’s system of procedures used to locate and repair leaking components (e.g., valves, pumps, connectors, compressors, and agitators) to ...

Strategy for Complying with Air Pollution Control Regulations in the Chemical Industry
Untitled Document The Clean Air Act (CAA) was originally passed by the United States Congress in 1970 and subsequently revised in 1977 for the purpose of protecting human health and the environment. In 1990, then-President George Bush signed the Clean Air Act Amendments. The far-reaching impacts of the 1990 amendments added significantly to the regulatory challenges ...

Global solution: Gas and particulate analysis in Cement industry
Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...
