s Suggested Operational BMPs: • Lightly spray water on the work site to control dust and grit that could blow away. Do not use oils for dust control. Never spray to the point of water runoff from the site. • Clean tools over a ground cloth or within a containment device such as a tub. • Consider using filtered vacuuming to collect waste that may be hard to sweep, such as dust on a drop cloth. • If conducting work in wet weather conditions, consider setting up temporary cover when scrap- ing or pressure-washing lead-based paint. • 452 BMPs for Goose Waste Desc '•tion of Pollutant Sources: Goose waste deposited near water or in water can •ntribute nutrient .nd algae growth. Goose feces may contain pathogens and contribute to the 'read of dis- eases. Swi• mers itch (schistosome or cercarial dermatitis)is caused by a parasite t :t can be spread by go•..e droppings, but does not mature or reproduce in humans. Pollutant Contr. Approach: To help decrease geese pollution to water so ces, remove waste periodically and use •-terrent management practices. Applicable Operati• naI BMPs: This BMP is for areas of chroni. accumulation of goose waste tha mpact stormwater systems. • If possible, pick up goose wa• e using shovels, brooms akes, power sweepers, and trash cans. Properly dispose of goos- aste in the garba• • Do not blow, sweep, or wash goose aste into .terways or storm sewer systems. • Regularly clean goose waste from area •f• ronic deposition where deterrence measures are impractical. • Do not feed wild geese or any other d anima • In recreational areas post signs •' couraging the fe-•ing of geese and other wild animals. Optional Operational BM r s: • Change the habitat fro • goose friendly to goose resistant. Re.uce lawn areas and increase the height of shoreli - vegetation (tall grass, shrubs); as geese a - reluctant to walk through tall vegetation. • Create a nat '.I geese barrier. 20 to 100 feet of herbaceous vegetation :t least 3 feet in height to dig ourage geese .A narrow,winding path through the plantings ill allow for beach access, ile preventing geese from having a direct line of sight through the • .nted area. • Ma bank slopes steeper than 4:1 to discourage geese by preventing a clear vie of the b. k top and potential predators. Or, separate the beach from the grass with a few -ep teps,which makes the ascent too difficult for most geese. 2019 Stormwater Management Manual for Western Washington Volume IV-Chapter 7-Page 611
