General Description of Project (N
: attach an 8.5” x 11” location map with enough detail to identify the loca-
ote
tion of the construction site, direction of stormwater flow, receiving waters within one (1) mile of the site, loca-
tions of off-site material, waste, borrow, and equipment strage areas, surface waters and wetlands, stormwater
discharge locations, and map section, township, and range as required by MDNR).
