Guidance regarding RISDISM Manual pg 3-7 "infiltration practices should
not be used where subsurface contamination is present from prior land
use due to the increased threat of pollutant migration associated with
increased hydraulic loading from infiltration systems, unless the
contamination is removed and the site has been remediated, or if
approved by DEM on a case-by-case basis."  


Please see attached document for the Department's guidance to assist
with the case-by-case basis.  The document is numbered so that you may
print it out and insert it as a page in your copy of the stormwater


If you have any questions, or need clarification, please feel free call
Alisa Richardson or Ernie Panciera at 401-222-4700.
