April 2016

Discussion of points raised by an attorney representing a couple of industries concerned over single source requirements.

I recently was considering the viability of the renewal of our NELAP accreditation and as a part of that process I sent an email to several clients which had in the past been required to use an accredited laboratory. Without the Method 25 audits and with the position of the NJ DEP that audits are required, the amount of revenue generated in that state compared to the costs of accreditation now have a significant differential. The options are varied: drop the accreditation until the audits are available, spend more money than is made from work in the state, charge a premium for work in the state to cover the accreditation costs, have a minimum billing for work in the state, or some similar guaranteed level of billing to at least break even. None of the options seems appealing, but there has to be a decision made on this issue soon. This is where the call from the attorney makes it even more difficult.

It seems the question I posed to some of our clients found its way to this attorney's desk along with some of my newsletters. The attorney wanted to know about my experiences with the accreditation programs from the first days in the early 1990s where we pressured SCAQMD to give us an accreditation through to the present. It seems the push to have the state accreditation programs pay for themselves, as well as having a restriction on only using accredited companies, has created a possible legal conundrum for a few of the states. Some industries believe the concern makes sense when taken as an overview. Most of the states only accredit the water sampling/analysis entities, so those states are dealing with very few niche methods. Of the few states who do accredit air sampling/analysis, most only accredit the much more common methods, such as the TO methods. The few states which provide accreditation for the multitude of air methods are where the problem seems to lie because it creates more sole source provider situations. This creates a possible case of unintended consequences that could also be taken as a planned action to create a monopoly under certain conditions.

The view seems to be that since there is a requirement for an accreditation from a state in order to work within that state on compliance projects, situations where the sole source monopolies or possibly no sources for the service at all are much more likely. The fact that the accreditation programs are becoming more income generation driven makes this problem take on a greater concern. When the costs were more reasonable the sole source or no source problems, while still very much a concern, did not have the more negative appearance it does now with the much higher fees being imposed. From a business perspective it is much easier to justify investing the cost of a few samples to become accredited as opposed to investing the cost of a few hundred, so I can see where the increased costs could have decreased the competition for some of the methods. The fact that the costs of even a secondary accreditation based on the accreditation by another state in the NELAC program are the same as a primary accreditation, reinforces the appearance of pure income generation as the goal. The cost structure would also tend to benefit the larger companies, which by being able to pay even higher fees could achieve more of a monopoly status within the state through the price exclusion of smaller competitors. This situation leads to the position by some industries that they are being required in certain cases to use one specific vendor, which may charge higher prices due to the lack of competition combined with the increased costs of accreditation. This is hard to refute given that there may be no competition due at least in part to the costs of accreditation. The appearance of a sole source situation opens the door to resist compliance testing connected to any sole source. The lack of any accredited source for certain monitoring places the state in a position where is cannot require that monitoring or if it allows a vendor without accreditation it negates the strict limit for only using accredited vendors in that state.

I am wondering what effect, if any, such litigation would have on the national accreditation program moving forward. The air methods seemed to have stalled somewhat compared to the water methods nationally and some future requirement to have two or more accredited sources for any work could slow that even farther. Of course, the requirement for accreditation within the state could be waved, but that too would seem to be counter productive for the accreditation program nationally. Because of these concerns I agreed to provide the requested information in exchange for the ability to freely discuss this in my newsletters in the hopes of some solution being found outside of litigation, which I feel would not seem to benefit anyone, especially not in the short term.

I know things of this nature tend to move slowly, or at least I hope the litigation moves forward slowly, but I am afraid the final outcome may be decided in the courts rather than with the groups involved. I hope it does not have the effect of limiting progress in the goal of improving our environment over the prior years. If it does have an impact, I cannot see it being anything other than another unintended consequence rather than some planned situation.

The new website is now up and running with all of the additional items we have meant to include over the years but did not because the hosting company was bought or sold yet again. I have been told by some of the younger people working on the project that we have an Easter Egg on the site, which is far different from the Easter Egg from my generation. Considering that my first programming was on the old Burroughs cards in Fortran, that mine was only the second engineering class to use calculators instead of slide rules, and my personal computer was a Commodore 64 with both a floppy and tape drive, the generational differences are significant.

Triangle NoTES — March 2016

Discussion of issues clients found with other sources for equipment and analysis during the period we were not an independent laboratory.

What has been so surprising to the people who, for whatever reason, had to use an alternative source for their analysis is the way things are done elsewhere.

The worst complaint was that the methods had been modified but that there had been no specific information provided for the modifications before the project was started. Once the results were submitted and questions were asked the modifications came to light. The problem was the modifications precluded the agency accepting the results thereby forcing a complete re-sampling of the source.

A close second was the dearth of information in the report, which consisted of essentially a table of results, a sparse narrative and a copy of the COC. This is a far cry from getting all of the data from area counts at the analyzer, response factors, dilution factors, sample calculations for every step and every piece of data for every sample should anyone wish to check the calculations. Over the years we have added more data to the report if even one regulatory agency requested it after receiving our report. We strive to have any data already in the report so if there is ever a question the answer is already available and documented. I know the program being use for calculations has been checked and the results verified by everyone here, a multitude of clients and regulators, and several auditors, but it never hurts to have just one more person follow up.

The one issue that completely surprised me was one I thought had been so completely discussed that everyone knew about it, which was making sure the return shipments were shipped legally and with as few problems as possible.

While it sounds a little counter-intuitive, if you meter 5 L of sample into a 6 L canister the volume of the sample is 6 L not 5 L. This is because the gas expands to fill the container albeit at a lower pressure. That is the reason we have the ability to determine the effect on the variables of pressure and volume when the temperature is constant. Using the formula P1V1 = P2V2 we can see how the pressure changes proportionally as the volume is changed. For example, a 3 L container with an absolute pressure of 760 mmHg will have an absolute pressure measurement of 380 mmHG if it is introduced into a 6 L container using this formula. The volume increased and the pressure in the container decreased. The inverse is also true, which means if the 6 L container had an absolute pressure of 760 the same sample in a 3 L container would have 1520 mmHg of pressure. The DOT defines volume of a gas sample as that of the container in which it is shipped as long as the absolute pressure of said gas is less than 15.22 psia per 49 CFR 173.306 (a)(4). Although most law enforcement agencies are not aware of the regulations or fines, the DOT has allowed anyone authorized to issue a travel citation to issue a citation for improper transportation of sample containers since 1988. This includes any state, county, city, or town police officer which may for any reason stop a vehicle for a travel violation. This includes personal and company vehicles in the potential for receiving a fine, but still not as likely to be fined as with a common carrier either.

Triangle NoTES — February 2016

This newsletter is to restart my newsletter program, to give information on how to seal Tygon tubing to a barb fitting, and to update the ownership of TES.

Yes, this is a return to the use of the newsletter I have used for the last couple of decades.

After my email concerning the potential leakage using Tygon tube on barb fittings, a few of you reminded me of some of the other ways by which one could also secure the tubing to the fitting.

One prominent tester, who many would recognize if I mentioned his name, uses small electrical wire ties, which work great in their experience. We have also used the very small electrical wire ties to hold 1/8 OD tubing onto the air actuators used on on our analyzers. This is mainly to prevent the connection from separating due to pressure, but it also prevents leakage, which would be very noticeable. Of course the smaller the tie is in thickness the more flexible it will be, and the more flexible the better the seal it will ensure. This may be the best solution for ease of application, simplicity of operation, and resulting seal.

Another solution, which is more of an emergency or field expedient solution, is to use the wire from the tags like we send with the samples. A portion of the wire may be wrapped around the tubing a couple of times, either after or between the barbs, and then twisted together to prevent it from becoming loose.

The reason I have reinstated the former newsletter is that we are again an independent laboratory effective the first of February after seven months as part of Enthalpy/Montrose. I have always liked the role an independent laboratory can play in this industry and I am looking forward to returning to that view by everyone. Invoices and reports will now come from TES and TES only from this point forward. The prior invoices from Enthalpy/ Montrose should be paid to them.
