WE HAVE MORE WORK TO DO!!!!
As we approach the end of the year please keep in mind there may be a NEW ballot from the TG 360 committee for the NEW SP0169-2007 revision in early January 2010. I am not sure what changes have been or will be made at this time, but we will see. The TG 360 committee would like to have the vote as early as possible next year so they can address any negatives at CORROSION 2010 in San Antonio, TX (next March).
You can log on to the Technical Committees Online Balloting Web page on the NACE.org website to see how many people responded and joined the voting pool as well as the individuals who submitted a vote with comments. Go to the NACE International.org website, then chose “Committees”, then “Online Balloting”, then Log in with your NACE number and Password. Once on this page, go to “TCC Balloting Results” and find the TG 360 group (page 9 when I looked). If you click on results you will get the voting information from the last ballot. A sample is below showing the number of folks who have signed up to vote and the number that actually voted.
Total Eligible Voters Number Voting Percent Voting
All Voters 391 270 69.1 %
STG Voters 313 222 70.9 %
If you click on the “Comments” you will be able to see those who voted to affirm, negative or abstain. You can also see all comments from those who made them. Reading these comments helps you to understand why many voted the way they did, as well as the concern expressed by some voters. These comments may help with your vote and how to make technical comments if your vote is negative. Please make “good” technical comments and arguments if you vote negative. If you vote for affirmation, you do not have to provide comments, but are welcome to do so. Abstaining votes do not count on the final pass/fail criterion, but you can provide comments if you wish.
Those who are on the voting list (391) can vote on the next ballot. You did not have to vote on the first ballot to vote on this one, but you must have signed up on the original voting list. So if you did not sign up on the “Balloting List”, you can not vote on the next ballot. See the Post below from Daniela Matthews at NACE.
If there is a doubt of whether you are on the balloting list, you should be able to contact daniela.matthews@nace.org.
To me there is so much evidence to show that the use of the “ON” -850 mV or more negative criterion (even without IR drop consideration) is valid. I will be posting some reports from the 1990 revision effort discussing many of the test site results for the PRCI report as well as some information from other companies. Basically, they show that if you can achieve a -850 mV “ON” potential (even without IR drop consideration) you can also achieve the 100 mV of polarization. I have also sent this information to Neil Thompson of DNV who is involved in the new PRCI study and report on whether the -850 mV “ON” criterion is valid. If you company is a member of the PRCI, please get involved.
I think we all understand that nothing is 100% and we can still have external corrosion in some cases even if we meet or exceed all criteria. Please pass along any data that may help the PRCI or TG 360 committee on their important missions. You can send it directly to the committee(s) or you can send it to me and I will forward it.
Many countries around the world will be relaxing this time of year because of the various holidays, especially in North America, but we must keep alert and provide the needed information to help this committee provide the industry with the best documents and reports possible. Without your help, they will not achieve that goal.
I am hoping that the changes to this new ballot will be allow us to all feel much more comfortable with what is written. Many are concerned about the regulatory implications in the various countries of the original proposed criteria. We will see what changes, if any, are in the new revision.
We need everyone who signed up to vote to vote! This is a critical document to the pipeline industry. No matter what your vote, please vote. Those who are not on the voting list, but have comments or issues you can pass those along to me and I will post them on the blog. I will also help anyone who is not sure how to word their comments with suggestions if there is a need.
I will pass along my thoughts of the new revision after it comes out for balloting. We also encourage others to make comments, no matter what your vote may be. We need to hear everyone’s opinion! Not just mine. Not just negative voters. Sharing information and concerns is how we are going to learn and make an educated decision.
Again, I will think the committee and all others who have worked so hard on this matter. We all want the same thing, a reasonable, sound document that works to provide the industry with guidance to provide safe, economical and environmentally friendly pipelines for the world’s future energy needs.

What happened to NACE?
You may remember “The National Association of Corrosion Engineers?” I wonder what those eleven men, corrosion engineers in the Pipeline Industry, would think of NACE today. A NACE that today finds itself in the position of writing Federal Code. A NACE that is contemplating changes to the core standard that has effectively and safely served the pipeline industry for the past 66 years. Prudent Operators have used the existing standard to protect the public and preserve valuable and critical assets.
I am not against revising the ST0169. I believe all standards should be under constant review with the goal of improving safety and asset preservation. Supporters of the revision argue that the off -.850 has scientific research behind it and contend that the on -.850 as put forth by Peabody has only empirical data to support it. How many leaks or ruptures have been associated with =<-.850 with current applied. The current revision being contemplated raises valid questions as to whether the off potential is a true IR free reading. Other’s who are far more qualified than I am have raised these questions and made convincing arguments and I will leave that to them.
My question is who should be reviewing and revising ST0169? If revised to the current recommendations this standard has the potential to add hundreds of millions of dollars to the cost of operating the country’s underground pipelines, and only bring about questionable improvements to safety. The stakeholders which include: the public whom the standard is designed to protect, the regulators who have the responsibility of codifying the standard, and the operators, who will have to absorb the cost of implementing the revised standard, should be debating, reviewing and revising the standard.
So back to my original question, what happened to NACE? When did we quit being an industry group with the goal of protecting the public and preserving the national asset that is the underground pipeline system? When did we decide that members who will be under no legal obligation nor incur the cost of complying with the standard get to set the standard? A quick glance at the membership roster of STG 35 shows only about 30% of the members are domestic operators. TG 360, about 30% of the members are domestic operators. Definition of Democracy “two wolves and a sheep voting on what’s for dinner”.
Whose fault is this? Mine, I am the corrosion practiconer working for a domestic operator who has decided that with budget pressures, expanding work load and shrinking staff , I am unwilling to dedicate the time to be actively involved in NACE except for the occasional trip to a conference.
I have been in the pipeline industry for over 30 years, and yet I recognize that with all of the scientific and technological advances made in the past 60 years it is time to move forward and take advantage of these tools. With the advent of high resolution ILI tools and the implementation of the IMP we have actual corrosion data for a segment of pipeline. Let’s incorporate this data into our compliance standard. Why expend time and resources to maintain an IR free -.850 or less with current applied to a segment of pipe that has no corrosion? With the baseline assessment nearing completion and reruns starting next year we will have accurate corrosion rates to work with. Give us credit for the hundreds of millions of dollars the industry has spent running high resolution ILI tools, give us credit for the hundreds of millions of dollars the industry has spent remediating to ASME B31.8S. Which would better ensure the safety and integrity of a section of pipeline, actual known corrosion data from an ILI or an electrical reading that at best tells us what the potential for corrosion is.
To summarize, if we are going to revise ST0169 then let’s revise it using all of the technological and scientific advances available to us today.

Comments on Voting for next ballot
I think it’s important to make the distinction between those in the balloting list and those who voted on the ballot. Anyone who responded “yes” to the correspondence that NACE sent out asking if they would like to join the balloting list can vote on the next ballot. The balloting list will remain the same. Not everyone who is on the balloting list voted on the ballot. The next ballot will not be restricted to solely those who voted, but it will be restricted to those who are part of the balloting list.

TG 360 Vote Results
The TG 360 committee meeting at CTW presented the status of the SP0169-2007 vote. The results were on the e-mail. The committee did not get the 66 2/3% they needed to pass on the first ballot! For those of us who did not think it was a good document at this point, this is great news.
As you can see there were not that many voters, but enough to stop the revision as written. The committee will now start over on the document. The same committee will stay together, with maybe a change or two. David McQuilling, who has been very vocal and against the revision and is now a committee member. I think this will be a good thing for a better voice and balance. I am not sure who else will remain or be placed on the committee.
The same voting group will be allowed to vote on the next version, but not new voters. I am not sure at this time if that means if you signed up to vote and did not vote that you can vote on the next ballot. Hopefully, that will be explained later. I thought they would have to start over since it is a new document, but apparently not.
Since they are starting over with the revision (actually adjusting it from the negatives) it will take a while, but they are attempting to get another vote before the end of the year. This means that we must stay alert to this vote and to the changes.
Please be aware that there will be another vote. I will try to keep you informed.
Polyguard hopes this blog site has been a help to those of you who do not have time or an opportunity to make all the meetings to speak your mind. Please feel free to comment as needed on the blog site, because NACE and some of the committee members do pay attention to what is being said.
Thanks for all the help and support,

Deadline is September 1!
We have one week left to send your vote into NACE for the SP0169-2007 revision. Please let me know if there are any issues or questions. I will help if I can.
We have all worked very hard. There is much more work to do! Even after the first ballot, there will likely be a re-ballot or two, so please stay in tune with the process. If you would to see what I say in my negative vote I will be glad to forward it to you if it helps.
I have strongly defended the use of the -850 mV or more negative “ON” potential. I have found some data that backs up the thing I have been saying for a long time. It is very rare to no meet a 100 mV of polarization if you also have an “ON” -850 mV or more negative. Also, most corrosion we find today has little to do with inadequate CP and more to do with the coatings we have used and are still using in some cases. There is too much proof! Too many years of data! Put it in front of the committee and let them see it.
The issues that we face are many. Please keep in mind that there are several parts of the document, not just criteria. We must look at all parts of the document. I personally think the coatings section has been greatly improved, even though there are some problems, but these can be corrected.
Thanks again for all the support and effort. In the long run, we hope we have a document that will provide the industry with the best possible standard that will provide many more years of guidance to controlling the external corrosion on pipelines.

What happened to NACE?
What happened to NACE?
You may remember “The National Association of Corrosion Engineers?” I wonder what those eleven men, corrosion engineers in the Pipeline Industry, would think of NACE today. A NACE that today finds itself in the position of writing Federal Code. A NACE that is contemplating changes to the core standard that has effectively and safely served the pipeline industry for the past 66 years. Prudent Operators have used the existing standard to protect the public and preserve valuable and critical assets.
I am not against revising the ST0169. I believe all standards should be under constant review with the goal of improving safety and asset preservation. Supporters of the revision argue that the off -.850 has scientific research behind it and contend that the on -.850 as put forth by Peabody has only empirical data to support it. How many leaks or ruptures have been associated with =<-.850 with current applied. The current revision being contemplated raises valid questions as to whether the off potential is a true IR free reading. Other’s who are far more qualified than I am have raised these questions and made convincing arguments and I will leave that to them.
My question is who should be reviewing and revising ST0169? If revised to the current recommendations this standard has the potential to add hundreds of millions of dollars to the cost of operating the country’s underground pipelines, and only bring about questionable improvements to safety. The stakeholders which include: the public whom the standard is designed to protect, the regulators who have the responsibility of codifying the standard, and the operators, who will have to absorb the cost of implementing the revised standard, should be debating, reviewing and revising the standard.
So back to my original question, what happened to NACE? When did we quit being an industry group with the goal of protecting the public and preserving the national asset that is the underground pipeline system? When did we decide that members who will be under no legal obligation nor incur the cost of complying with the standard get to set the standard? A quick glance at the membership roster of STG 35 shows only about 30% of the members are domestic operators. TG 360, about 30% of the members are domestic operators. Definition of Democracy “two wolves and a sheep voting on what’s for dinner”.
Whose fault is this? Mine, I am the corrosion practiconer working for a domestic operator who has decided that with budget pressures, expanding work load and shrinking staff , I am unwilling to dedicate the time to be actively involved in NACE except for the occasional trip to a conference.
I have been in the pipeline industry for over 30 years, and yet I recognize that with all of the scientific and technological advances made in the past 60 years it is time to move forward and take advantage of these tools. With the advent of high resolution ILI tools and the implementation of the IMP we have actual corrosion data for a segment of pipeline. Let’s incorporate this data into our compliance standard. Why expend time and resources to maintain an IR free -.850 or less with current applied to a segment of pipe that has no corrosion? With the baseline assessment nearing completion and reruns starting next year we will have accurate corrosion rates to work with. Give us credit for the hundreds of millions of dollars the industry has spent running high resolution ILI tools, give us credit for the hundreds of millions of dollars the industry has spent remediating to ASME B31.8S. Which would better ensure the safety and integrity of a section of pipeline, actual known corrosion data from an ILI or an electrical reading that at best tells us what the potential for corrosion is.
To summarize, if we are going to revise ST0169 then let’s revise it using all of the technological and scientific advances available to us today.
