A few updates from my site visit yesterday. There is a large rut that I asked to be filled in with some of the good organic material that I saw available onsite. Then I asked that they native riparian seed and coir fiber mat the area. I am hopeful that this will be able to be satisfactorily restored. I still haven’t received the marked up permit drawing with the polygon of the impact area but I will push to get that today. The water looked really clear downstream and I was able to mark the extent of where I was seeing sediment deposits ~ 60’ downstream of our permitted impacts. I didn’t want to send the bucket brigade down there to retrieve without concurrence from you all that retrieval would be the best action right now. If we were to do this I would want to temporarily install a few wattles or sandbags at that location since will likely stir things up. We can always wait and see if the water level drops some but we are expecting more rain. If you all would like us to move on this now we surely will. I will be out onsite again today to monitor progress. Feel free to call me on my mobile.

The project received over 4.5” or rain over the weekend which caused erosion around the inlet of the temporary diversion pipe and the temporary diversion channel that the contractor had just finished prior to the weekend (this was all constructed within the originally permitted impacts but the contractor will still need the additional impacts that we submitted in our recent modification request for the wing wall installation phase). The diversion channel also received sediment from undermining of the silt fence that was installed along the top of the bank of the diversion channel. I did not see any deposits of sediment downstream but it looked more turbid and it is safe to assume a good amount of sediment made it’s way offsite. We will keep our eye out as the water level drops for anything that we may be able to retrieve. Part of the undermining of the silt fence was due runoff from a large a stockpile site (spoils from the digging of the channel and the adjacent basin) that was located less than 50’ from the diversion channel. I asked the contractor to relocate the material and informed them that they need to treat the diversion channels as if they were active streams with regards to stockpiling material. The contractor installed a fill burrito (fill wrapped in geotextile fabric) to dike off the temporary diversion channel and reroute water back through the JS since they had not yet grubbed the banks. The water looked clear running through the JS and I did not see any erosion. I also informed the contractor that they needed to use sheet pile or another approved impervious dike method while they fix the pipes and diversion channel as the fill burrito is not an approved method. Last but not least, the contractor made a bad situation worse. In an effort to dike off the inlet of the temporary diversion channel, the contractor drove their excavator across an area of wetland where we are not permitted for any impacts. The safety fence was laying to the side and had been caught in the tracks of the excavator. Evidently the contractor did not think about what they were doing in their urgency to dike off the temporary diversion channel. Our initial estimates of this unpermitted wetland impact area is approximately 657 square feet (Y30RPA ~16+00 98L). They had their surveyors out this evening and we will send an accurate square footage and marked up permit drawing of the area tomorrow. Ben Meyer was able to send me a photo of their restoration efforts of where the contractor tried to place the material back in the ruts. I will be onsite again tomorrow to get some additional photos and monitor how they are proceeding. I will provide updates. I am pretty sure a good portion of the unauthorized impacts are in the area of additional temporary impacts that we recently submitted a modification request for, so that is something else we need to consider. I am very sorry to have to report this and I am pretty disappointed in the many compliance issues that transpired so quickly at this site. We are going to have to monitor this contractor’s activities more closely to make sure they our meeting our expectations for environmental compliance.
