Which of the following is NOT a regulated LDA exemption?

The understanding of regulated LDA (Land Disturbance Activities) exemptions is essential for stormwater management inspections. In this context, single-family residences built on more than one acre are generally subject to regulations rather than exempt from them.

This is rooted in the goal of stormwater management strategies, which seek to mitigate the impact of land disturbance on water quality and prevent flooding. When residences are constructed on larger parcels of land, they often involve more significant site alterations, such as land grading, vegetation removal, and increased impervious surfaces, which can significantly impact stormwater runoff.

The other scenarios listed are recognized as exemptions due to their specific nature or regulatory provisions. For example, permitted mining operations or emergency response activities are typically regulated differently due to their unique circumstances and immediate benefits they provide, while livestock feedlot operations may fall under different agricultural regulations rather than the standard land disturbance regulations. Thus, these activities do not require the same level of regulatory oversight as developments involving new single-family homes on larger lots, making the exemption status of single-family residences on more than one acre appropriate for regulatory coverage.
