Editor’s Note: February 2012 — 3 Comments

  1. Thank you for your well-reasoned article. I didn’t see your link to additional resources. Will that be in the print version only?
    If your readers want to look at the web’s most in-depth source of news and information on this topic including videos from the researchers and an up-to-date list of where there are bans, then please consider my site.

    • The full article on Coal Tar Sealers will be featured in full on the site shortly. This article here is simply the Editor’s Note from page 6 of the February 2012 issue of The Municipal.

  2. Understanding that there are 2 opposing sides – I believe that the following can be considered – Independent!

    Independent – (adj) – Bing Dictionary
    1.not controlled by another: in politics, free from the authority, control, or domination of somebody or something else, especially not controlled by another state or organization and able to self-govern
    2.able to function by self: able to operate alone because not dependent on somebody or something else
    3.self-supporting: not forced to rely on another for money or support

    The following is “Independent” –
    Valle, S., Panero, M., Shor, L., Pollution Prevention And Management Strategies For Polycyclic Aromatic Hydrocarbons In The New York/New Jersey Harbor. New York Academy of Science, September 2007.

    “Today, a general consensus of literature reports two major national and global sources of PAHs in the environment: 1) incomplete combustion of organic matter, especially common, nonpoint activities that utilize modern emissions controls (e.g., cars) or less common activities with no emissions control (e.g., tire fires); and
    2) releases of petroleum, including oil spills and illegal dumping. Major sources include forest fires, motor vehicle emissions, open burning, domestic fireplaces, and spills and dumping of petroleum products. (page 47)

    “Our estimates indicate that transportation-related activity (i.e., on-road and off-road engine exhaust, tire wear, and motor oil disposal and leakage) is the source category contributing most greatly to total loadings of PAHs”. (page 27)

    Study determined that refined tar based sealer to be a minor source of PAHs to the NY/NJ harbor watershed (less than 1% total contribution). (pages 21 & 26)

    NYAS reconsidered and dropped PAH loading estimate recommended by COA.

    NYAS rejected COA photographic sealer wear-off estimation.

    NYAS saw flawed conceptual study design and flawed statistical analysis (errors in calculations) in the COA studies.
