Answer: Not enough information provided. We will need to know if the sites are contiguous or not. If the sites are not contiguous, then the company must submit a separate NOI and prepare an individual stormwater pollution prevention plan (SWPPP) for each site.

However, if the facilities are located on adjoining property, then one SWPPP and one NOI could cover that entire site. If they are on adjoining property there may be different conditions that apply to each site and those different conditions/requirements must be reflected in the SWPPP and NOI. In Section D.5 of the NOI, the operator must identify the primary industrial activity at the facility. In Section D.6, the operator is asked to identify the co-located industrial activities at the facility; this is where the facility will indicate the specific industrial sector corresponding to the activity taking place at the adjoining property.
