Which of the following best describes a LUP Type 3 Site?

• A. A site under 10 acres with no direct discharges
• B. A site larger than 50 acres with no receiving water impacts
• C. A site larger than 30 acres with direct discharges to receiving waters
• D. A site under 30 acres with indirect discharges

Answer: (C)

LUP Type 3 sites are categorized by size and how stormwater leaves the site. This category applies to sites larger than 30 acres that discharge directly to a receiving water. The emphasis is on the combination of a large site and a direct connection to streams, rivers, or lakes, which typically requires more stringent controls in the SWPPP due to the higher potential pollutant load. Smaller sites (under 30 acres) or sites that discharge indirectly (to a drainage system that ultimately reaches a receiving water, or no direct discharge to waters) fall into the other categories and do not meet the Type 3 criteria.
