ALL4 Air Quality Modeling Update
April 2014 | Dan D.
As it’s been over a year since my last air quality modeling-related 4TR article, I thought it appropriate to provide a general status report on the air quality modeling updates that have occurred over the last year. There are a number of items that warrant discussion around their updates and the potential impacts on the regulated community...

SO2 NAAQS Implementation: The Great American Update
March 2014 | Colin M.
Since the 1-hour sulfur dioxide (SO2) National Ambient Air Quality Standard (NAAQS) became effective in August 2010, ALL4 has been tracking it every step of the way. Its implementation has proven to be chaotic at times and quiet at others. As we are ramping up into our air regulatory reporting obligations for 2014, U.S. EPA’s implementation of the 1-hour NAAQS is ramping up as well. This article will discuss where the 1-hour SO2 NAAQS has been, where it is going, and what you can do to plan for 2014 and beyond. Before we can look forward, we need to revisit how we got to this point.

How to Get the Most Out of Your Boiler MACT Energy Assessment
February 2014 | Lindsey K.
Congratulations! You’ve made it through the first year of planning for compliance with the Major and Area Source Boiler MACT rules. That means there are two years left for major sources to come into compliance by January 31, 2016 (or January 31, 2017 for those who requested and received a one-year extension), and just shy of two months left for area sources to come into compliance by March 21, 2014...

ALL4 Staff Weigh In On Air Quality Expectations for 2014
January 2014 | Susie B.Dan D.John E.Ron H.Dan H.Lindsey K.Colin M.Roy R.John S.Eric S.Megan U.Mark W.
So, what happened to 2013? Don’t look now, but it is already history along with several substantial events including (but not limited to) the rollout of the Affordable Care Act (aka Obamacare), another “fiscal cliff” standoff, a federal government shutdown, the early signs of a broad(er) economic recovery, a cowardly act in Boston, a new Pope, and the loss of Nelson Mandela. Several less noteworthy 2013 events (but still worth mentioning – at least from my perspective) include...

Major New Source Review (NSR) - Planning for Success
November 2013 | John E.
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

PSD and the Dreaded Major Modification
October 2013 | Roy R.
The implementation at the state level of the major New Source Review (NSR) rules that include both prevention of significant deterioration (PSD) and nonattainment new source review (NNSR) have evolved over a long period of time. During the last decade that evolution has been substantially impacted by the “NSR Reform” revisions of 2002; the regulation of particulate matter less than 10 microns (PM10) and particulate matter less than 2.5 microns (PM2.5); and the seemingly routine changes in form and reductions of national ambient air quality standards (NAAQS) following required reviews...
