Future Environment Designs Celebrates 30 Years in Business in October. What the heck is SNUR?


View Do As I Say, Not As I Did by Angelo Garcia III

On October 5, 1988, Future Environment Designs Inc. was founded by Angelo Garcia, III.  When we started the company, our only thought was, considering the companies we worked for, how hard could this be.  Well 30 years later here we are a slightly different focus from when we started, but the same drive of trying to provide the best service we can for our clients.  Since the official date of our anniversary falls when we are in the Plattsburgh area, we are starting the celebration at 4:30 PM on October 5, 2018, at the Valcour Brewing Company, 49 Ohio Avenue, Plattsburgh, NY 12903.  The second date of our celebration will be held at 5:00 PM on October 9, 2018, at Sapsuckers Hops & Grub, 287 Main Street, Huntington, NY 11743.  We hope to see you at one of the events to help us celebrate our 30 Years!

In honor of making it to 30 years, we have written a book called "Do As I Say, Not As I Did - Thinking Of Opening a Business, Some of the Things You Should Consider".  The book is available through Blurb as a hardcover or a pdf.  If you bring the book to one of our classes or one of our Anniversary events, we would be honored to sign it for you.  We wrote this book to discuss our experiences over the 30 years and to provide you with a resource if you ever consider opening your own business.

Over the 30 years, we have seen lots of changes in the industry and outside of the industry.  It is interesting to remember when we started we used beepers and phone cards to stay in communication between the field staff and the office.  Now, most people have cell phones.  We used typewriters to fill out ACP5 forms.  Now, they are done online.  We used to provide students course manuals that were hundreds of pages and took forever to find what you were looking for.  Now the manuals are electronic/digital and you can do a keyword search to find what you are looking for in minutes or even seconds.  But with all this advancement the work still stays the same.  Workers still need to wear respirators to protect themselves, still need to take showers to leave the contamination at the work site, still need to use water to keep dust levels below exposure levels, and create a negative pressure inside the work area to prevent the escape of asbestos fibers from the work area.  So while a lot has changed and a lot has still stayed the same!

When we opened our business doing consulting work in the asbestos industry, we were asked by our mentors and friends why.  Many of them thought or felt all the asbestos will be removed in 5-10 years.  It is interesting that not only is all of the asbestos not removed but, after 30 plus years of wanting to ban asbestos, the Environmental Protection Agency (EPA) instead of an outright ban of asbestos has actually proposed a rule that could allow asbestos to be used in products that they have determined are no longer available.  This proposed rule is called SNUR (Significant New Use Rule).  The rule would require manufacturers and importers to receive EPA approval before starting or resuming manufacturing and importing or processing of asbestos.  Currently, new uses of asbestos were banned under the original Toxic Substance Control Act - Asbestos Ban and Phase Out Rule issued in 1989, though portions were overturned the ban on new commercial uses after August 25, 1989, remains.  Materials not subject to the Asbestos Ban and Phase Out Rule and hence are the subject of this SNUR are:

  • Asbestos arc chutes
  • Asbestos pipeline wrap
  • Asbestos separators in fuel cells and batteries
  • Asbestos-reinforced plastics
  • Beater-add gaskets
  • Extruded sealant tape
  • Filler for acetylene cylinders
  • High-grade electrical paper
  • Millboard
  • Missile liner
  • Roofing felt 
  • Vinyl-asbestos floor tile 
  • Adhesives and Sealants 
  • Roof and Non-Roof Coatings 
  • Other Building Products (other than cement product)
As you may wonder and as many others have, why a SNUR?  Why not a flat out ban?  Why else but to allow asbestos to be used by certain industries, for example, the chlor-alkali industry which currently is the primary importer of asbestos still today!  In 2016, EPA noted that 340 metric tons of asbestos were imported into the United States all of it used by the chlor-alkali industry.  We think the list of materials that are affected by the SNUR is interesting, imagine if they allowed the return of asbestos use in floor tiles, roofing felts, electrical paper, adhesives and sealants and roof and non-roof coatings.  All of these are building materials that would be required to be inspected and determined if they contain asbestos.  If they contain asbestos, they will have to be removed as asbestos-containing materials.  The asbestos abatement industry may never go out of business if that was the case.  So maybe, we'll still be here for another 30 years.  Imagine that!

Asbestos Dust Sampling in New York State

In our recent asbestos inspector/designer classes we have been informing them about the New York State (NYS) requirements for dust/surface sampling.  Under NYS Department of Labor (NYSDOL) Industrial Code Rule 56, dust and debris are listed as suspect miscellaneous asbestos containing materials (ACM).  Meaning that if the building was built pre-1974, this debris and dust that is visually assessed by the inspector shall be treated and handled as ACM and shall be assumed ACM, until bulk sampling is done.  Well the question comes how do you bulk sample debris and dust?

Asbestos Inspector Initial Course
The best way is to collect the debris and dust by scraping it into a asbestos sample bag using a knife or a scraper.  This material could then be analyzed using NYS Department of Health (NYSDOH) Environmental Laboratory Accreditation Program (ELAP) method 198.1.  NYSDOH ELAP method 198.1 is the standard polarized light microscope method utilizing dispersion staining and point counting.  

Another popular method for collecting debris and dust samples is the American Society of Testing and Materials (ASTM) standard "D5755 - Microvaccum Sampling and Indirect Analysis of Dust by Transmission Electron Microscopy for Asbestos Structure Number Concentrations"  The D5755 method requires vacuuming a known surface area (100 squared centimeters is mentioned in the standard but it could be larger or smaller).  The vacuuming is done with a standard 25 or 37-millimeter air sampling cassette (the air sampling cassette should have a mixed cellulose ester (MCE) or polycarbonate (PC) filter membrane with a pore size less than or equal to 0.8 micron) and an air sampling pump.  A plastic tube should be attached to the inlet orifice to act as a nozzle and should be cut at a 45 degree angle.  The air sampling pump should be calibrated to run at 2 liters per minute.  The D5755 method incorporates a method of analysis for the sample, however, in NYS that method cannot be used.  According to the NYSDOH ELAP Frequently Asked Questions (FAQ) number 8, "all bulk samples collected must be analyzed by ELAP approved methodology at an ELAP accredited laboratory.  ASTM method D5755 ....... are not certified as ELAP approved methods of analysis."  The method of analysis that shall be used, especially if you want transmission electron microscope analysis, is NYSDOH ELAP method 198.4.

ASTM standard "D6480 - Standard Test Method for Wipe Sampling of Surfaces, Indirect Preparation, and Analysis for Asbestos Structure Number Concentration by Transmission Electron Microscopy" is another method for collecting debris and dust samples.  This method involves wiping a surface of a known area (100 squared centimeters is mentioned in the standard but it could be larger or smaller) with a wipe material (particle free, sealed edge, continuous filament cloth sampling medium such as a clean room wiper) to collect a sample.  See the video below by IAQTV for visual instructions on collecting this type of sample:

  

The D6480 method also incorporates a method of analysis for the sample, however, again in NYS that method cannot be used.  According to the NYSDOH ELAP Frequently Asked Questions (FAQ) number 8, "all bulk samples collected must be analyzed by ELAP approved methodology at an ELAP accredited laboratory.  ASTM method......and D6480 are not certified as ELAP approved methods of analysis."  The method of analysis that shall be used is NYSDOH ELAP method 198.4

The interesting part about this is, NYS ELAP approved laboratories should be advising asbestos inspectors they cannot use the ASTM methods of analysis.  However, we've heard of several times when this has not occurred.  According to the above information, an inspector should be getting results for the samples collected in percent by weight (%), which they can then use to compare with the Environmental Protection Agency's (EPA's) definition that an asbestos containing material contains greater than 1% of asbestos by weight.  If they use the ASTM methods they will get results of structures per square centimeter.  There is no government standard to compare these results to and be able to give a determination is the material asbestos containing or not.  However, that has not prevented individuals from determining that areas are contaminated, or that debris or dust is ACM.  This has cost owners thousands and millions of dollars to cleanup areas based on this analysis.  It is even more interesting to note that ASTM in the "Significance and Use" section states:
  • This test method does not describe procedures or techniques required for the evaluation of the safety or habitability of buildings with asbestos-containing materials, or compliance with federal, state, or local regulations or statutes.....
  • At present, a single direct relationship between asbestos sampled from a surface and potential human exposure does not exist.....
When using the two ASTM methods, an inspector must be very careful in collecting the samples and interpreting the data that you get from these methods.  Experience and knowledge are key.

NYS Department Of Health Vermiculite Clarification

New York State Department of Health's (NYSDOH) Environmental Laboratory Approval Program (ELAP) has released an update that revises FAQ #10 from the 4/8/11 FAQ document.  This update is posted at:
http://www.wadsworth.org/labcert/elapcert/forms/Vermiculite%20Guidance_Rev062212.pdf.  

The revision separates vermiculite into two types.  Vermiculite material used for thermal systems insulation (TSI), surfacing materials, and other miscellaneous ACM (including but not limited to:  existing or new surfacing material, plaster, pipe lagging, and sprayed-on fireproofing) or vermiculite material used for attic fill, block fill, and other loose bulk vermiculite material.  For the vermiculite material used for attic fill, etc. nothing has changed.  We still cannot analyze it and material must be assumed to contain asbestos and designated an asbestos containing material.

New Evaluation for Surfacing Material Containing Vermiculite
For the vermiculite used for TSI, surfacing material, etc. anaylze by ELAP certification manual item 198.1 (polarized light microscopy [PLM] friable method).  Vermiculite evaluation shall follow these three steps:
  1. If vermiculite is calculated to be less than 10% of the entire material composition and no asbestos fibers are detected, the material may be reported as non-ACM.
  2. If any asbestos fibers are identified, analysis must proceed according to Item 198.1 PLM and reported as ACM according to Section 6.3.
  3. If vermiculite is calculated to be 10% or more of the material, the material must be reported as ACM.
According to NYSDOH ELAP the reason for the difference is that vermiculite used for TSI, etc can be more constrained that loose fill, there is less of a public health concern pertaining to airborne asbestos fibers following disturbance.
