This week I have had two projects returned to me from the preliminary construction review with the same comment. I have never seen this comment before and am a little perplexed. The comment states that it is unclear if the plan includes the proper measures for the prevention of air pollution (dust and particulate matter) and the technical advice is to provide a detailed narrative describing the measures taken for the prevention of air pollution. In both instances, our plan included the gravel construction entrances/ exits, which used to be enough to satisfy this portion of the credit. What else do we need to prove compliance? There was also some watering of the site that happened that we will include in the narrative, but I'm wondering if there is something that I'm missing? Does anyone else know of strategies that the reviewers are looking for?
