QUESTION:

Do any of the following conditions apply? (NOTE: If any condition applies, you do not need to answer the remaining questions.)

  • The site is located within a DWSMA, wellhead protection area, or within 200 feet of a drinking water well, and infiltration is not allowed by the LGU

Yes

  • Karst is present within 1000 feet of the site and the BMP cannot be relocated so that it is more than 1000 feet from karst

Yes

  • Shallow groundwater or shallow bedrock is present within 3 feet of the bottom of the BMP and the BMP cannot be relocated or raised in elevation to achieve a 3 foot or greater separation from bedrock or groundwater

Yes

  • Contaminated soil, contaminated groundwater, or hotspot runoff is present on the site and cannot be isolated or mitigated

Yes

  • Soils on the site have an infiltration rate of less than 0.2 inches per hour, the BMP cannot be relocated to areas with a higher infiltration rate, and the BMP cannot be sized to drain within 48 hours (24 hours in locations that are tributary to trout streams)

Yes

  • Soils on the site have an infiltration rate greater than 8 inches per hour, the BMP cannot be relocated to an area with an infiltration rate lower than 8 inches per hour, or the subgrade cannot be modified to slow the infiltration rate to less than 8 inches per hour

Yes


No
