 Appendix B
BEST MANAGEMENT PRACTICES (BMP) FOR THE USE AND PROTECTION OF
WOOD IN THE MARINE ENVIRONMENT
1.
Specify treated wood in all circumstances unless it is clearly evident that plastic-covered
or untreated wood can provide the required performance.
Plastic-covered wood can be specified and used in accordanice with NCEL Tech Note
TN-1811. Questions concerning this TN should be addressed to the Waterfront Materials
Division of the Naval Facilities Engineering Service Center (NFESC) at (805)982-1070.
Untreated wood should be expected to last from 6 months to two years.
2.
For treated wood, specify the appropriate material in terms of performance as defined in
the American Wood-Preservers' Association (AWPA) Standards.
You may obtain current standards by contacting AWPA at PO Box 286, Woodstock, MD
21163-0286 or (410) 465-3169. Questions concerning these standards can be addressed directly
to AWPA or contact your local EFD Applied Biologist or NFESC.
3.
If a project involves the installation of a large volume of treated wood in an area of low
water volume and limited flushing action or there is any cause for environmental concern, a site-
specific risk assessment is highly recommended.
Consult with your environmental office early in the design phase; consider the inclusion
of a risk assessment in the NEPA documentation. At present there is no NAVFAC developed
standard procedure or recommendation for accomplishing such a risk assessment. A computer
spreadsheet program for evaluating the risk of treated wood usage in aquatic environments has
been developed by the Western Wood Preserver's Institute (WWPI) and may be applicable.
Consult with NFESC Waterfront Materials Division on its usage.
4.
Specify that treated wood be produced in compliance with current industry BMP
Industry BMP describe proper procedures to be used by wood treaters and include
criteria for treatment, post treating, maximum chemical loading, and visual inspections. Current
BMP for creosote, arsenical salt-treated, and dual-treated wood can be obtained from the WWPI
at (800) 279-WOOD or by contacting NFESC.
5.
Specify that treated wood be inspected by an independent agency and again on site before
installation.
