Fir Poles and Fumigants

From the February 1977 EPRI Journal: EPRI reports that about 500,000 utility poles made from fir trees are replaced annually at a cost of $500 each. EPRI is evaluating fumigants to control decay that could add 10 years to the life of a pole, saving utilities about $9 million per year.
