Shen - yi Anka Gelbin (spelling probably butchered) who is the head of Accustandard's custom synthesis group contacted me today regarding a message I le ft asking if they were willing to make this standard available. She said it would probably be a four figure (some multiple of $10,000) project. I would think that the companies ordering the standard who would have to pay for it, but she said they might n eed money to get the project off the ground. Her phone # is 203.786.5290 ex 108. I don't know how the standard manufacturers decide what should and shouldn't be in a given standard mix, if they're in contact with someone in EPA. At any rate, it sounds l ike they'd be willing to make this compound as a standard if we give them 4 - 6 weeks lead time and money

Joe Hope yo u're doing fine on this fat tuesday eve. OS W is looking for a standards manufacturer to supply this carbamate pesticide as an analytical standard. Do you have an idea of where they mi ght be able to obtain it? If not, do you have a standards supplier whose service you wou ld recommend for them to get a custom sy nthesis quotation from? The commercial lab person who did some of the leg work to try to get a standard of this compound already was told by Ultra, Chem Service, SPEX Certiprep, O2SI, and Crescent Chemical that they wouldn't provide it as a custom sy nthesis (details in the e - ma il thread below). I sent an e - ma il to Michele Schantz at NIST too to see if she could provide any leads. Troy J Strock, chemist US Environmental Protection Agenc y Chicago Regional Lab 536 S.

Shen - Yi, Please see the following message thread regarding the analytical standard we are looking for. It seems that suppliers are unable to provide a custom standard due to lack of raw material.

- cumenyl methylcarbamate Dear Ms. Paddock: Thanks for your inquiry. As we discussed via phone on January 10, I ag ree with you that the compound Mr. Barry Lesnik suggested, promecarb (C12H17NO2, RCRA waste code P201, molecular weight 207.2718) has a different molecular formula and molecular structure than the reference standard you are searching for, m
- cumenyl methy lcarbamate (CAS Number: 64
- 00
- 6, RCRA waste code P202, C11H15NO2, molecular weight 193.245). Even though Promecarb is a very similar carbamate in chemical structure, but it would be an inappropriate standard for the quantitation of m
- cumenyl methylcarbama te. I did check with a number of large chemical standard suppliers and it appears at one point this was a commonly stocked standard. However, I suspect that the demand has dwindled to the point that it is no longer feasible for them to keep it as par t of their common catalog standards All of the suppliers I checked do have the ability to prepare custom standards, and this would probably be the best option for m
- cumenyl methylcarbamate. Here are the links to the suppliers I checked: http://www.o2 si.com/ http://www.alfa.com/alf/index.htmhttp://www.accustandard.com/

http://www.isotope.com/cil/products/index.cfm http://www.rt
- corp.com/default.aspx http://www.eraqc.com/ Also, m - cumenyl methylcarbamate is a RCRA target analyte listed in Method 8318 and many of the standard suppliers do offer calibration mixes for Method 8318, however, m
- cumenyl methylcarbamate is not included. This is further indication that the monitoring demand and analysis for this compound has decreased such that it is no longer routinely analyzed. To place a custom standard order for m - cumenyl methylcarbamate, you may contact Ms. Donna Theroux of Customer Service of ULTRA Scientific at 1

Thank you for your email, Nancy. As I explained in our conversation, Shen
- yi may be able to help with general pointers or insights regarding standard development working with NIST, and perhaps suggestions in addition to what Barry has already provided. Also she can then better advise the division director and me concerning the scope of this issue and any options there may be for moving forward. FYI, the suggestion you made to Barry of documenting for your compliance files that procarbemar would be anequival ent standard is not necessarily a straightforward or quick thing

to accomplish; as I explained Shen
- yi currently has numerous competing d emands on her time due to Barry's retirement. (I will also forward to Shen
- yi the information that Barry left you on y our voice mail.) Most of us will also be out until Jan. 2 or 3, so we can resume discussion at that time. Best wishes for a happy holiday.

- cumenyl methylcarbamate Jan, Thank you for taking the time to discuss my issue this morning. To summarize, I work for a hazardous waste incineration facility and am responsible for LDR compliance. Incineration residues are periodically sampled and analyzed to verify that all UTS are met. I was recently contacted by the outside laboratory we use to provide data for the carbamate compounds and was told that a standard for the compound m - cumenyl methylcarbamate (waste code P202) can no longer be found. I checked with all of the other outside labs that we use and they in turn, checked with their suppliers; the standard is not available, not even in Europe. Barry Lesnik stated that we should use promecarb as the standard for m - cumenyl methylcarbamate. I would be happy to do that, but since promecarb represents a different waste code (P201,) has a different molecular f ormula and molecular structure, I requested something in writing from Barry to document this choice for our compliance files. Barry has not yet replied to the December 13th request I made via e
mail. I understand that Shen - Yi Yang will likely be ta king over this aspect of Barry's work upon his retirement. If she can discuss this issue with me and verify his guidance or provide an alternative, that would be greatly appreciated. After today, I will be out of the office until January 2nd. I lookf orward to discussing the situation with Shen
- Yi at her earliest

convenience. My contact information can be found below. Thank you again for your time this morning and I hope that you enjoy this> Holiday Season! Sincerely, Nancy Paddock Environmenta l Engineering Specialist Veolia ES Technical Solutions 618.271.2804 ext. 115
