Did you know that MacDonald-Miller helps the aquatic habitat of Puget Sound? Since 2010, MacMiller pre-fabrication shop has been operating with a Stormwater Pollution Prevention Plan, otherwise known as a SWPPP. Part of this plan includes quarterly stormwater sampling, testing, and reporting to the Department of Ecology. The stormwater leaving the shop yard is tested for six different pollutants with benchmark levels not to be exceeded. Because of the nature of our business, for two of the pollutants, zinc and copper, it was nearly impossible to reach benchmark levels.
