another BMP, such as a grassed Swale, either before or after the dry pond to achieve the 85% TSS removal Dry ponds only account for 50% My time line is running about 60 days for a review In order for Mr English to be open on June 1, he should have the application in to me ASAP And make it perfect - look at the previous comments I had for Dale's proDect and try to address everything Don't leave anything blank on the application If something doesn't apply ( and make sure it really doesn't) mark it N/A Be sure to send me the original signatures Include a signed Operation and maintenance plan Make the calculations as detailed as possible, and taking it step by step Show how all the numbers were obtained And check the math for simple errors in addition and multiplication Don't forget to have the engineer seal the calculations Make sure the plans have dimensions, details, contours (existing and proposed), show the drainage area, and a good vicinity map Linda Bonkers wrote *Linda,* **

Site Subject: Re 211 Site From: Linda Lewis <Linda Lewis@ncmail net> Date: Mon, 22 Mar 2004 14 10 41 -0500 To: Bonkers <bonkers@mfire com> Steve The main issue is no longer the status of the pond, although that remains one issue The main issue concerns the "Plan Revision" that was sent to the Division by Mr English, apparently Only the permittee can submit a plan revision Mr English sent in a plan revision to revise a permitted drawing for a permit that HE DOES NOT OWN He represented himself as the owner of the offsite facility, which is not true The pond has been permitted to Mr Gordon Lovingood, C-3 Investments, and even though the pond design does account for the runoff from the outparcel, if Mr English did not secure provision to use the pond in his sales contract, then I can't force Mr Lovingood to accept it That has to be between the two of them, and if they can't come to terms, I can't force it If Mr Lovingood doesn't want to allow Mr English to use the pond, then it becomes a civil matter As the owner of the outparcel, Mr English should have applied for an offsite permit and received his own permit, regardless of the fact that the disturbed area was <1 acre The parent tract of land already received a land disturbing permit, so this is Dust a continuation of the original disturbance Mr English needs to submit an offsite permit application as soon as possible Linda Bonkers wrote *Linda,* ** *Ok, things are beginning to come together now I'm getting old, had to stop and think, lot * *When I was looking thru your file in your office, on the Hampton Inn some time ago, I noticed Bryan English's name was on one of the original permits Then it went over to Lovingood's name, so he could commence the motel construction * ** *From what I see, the pond, as it is built has not been completed The timber forebay hasnt been installed Crying shame is the material is on sites Lovingood, for some weird reason let them leave without completing it Thus, the reason Phil Tripp hasnt completed and submitted the pond certification * ** *The entire site has been permitted, in fact up to 80% impervious for our section From memmory, around 43,000 s f , and we used approximately 26,000 s f And this was to be directed to that pond that was pre -designed for the higher square footage area Thus a net deduct in volume as originally proposed and permitted * ** *Also, be aware that the current land area under construction is 0 99ac Less than the 1 acre threshold requiring a DWQ permit I say this for your information We do not wish to get into a rock throwing contest with anyone If you can put pressure on Lovingood to complete his originally permitted pond construction, and have the engineer of record (Tripp) to complete and submit that pond certification, we will be happy to re -certify that pond once our portion of the pro3ect is complete That should take care of all your woes * ** *Apparently Lovingood is being cantankerous, and going back on original agreements and the failure to follow thru on his construction as permitted ** *Bryan is wanting to play ball "soft ball, not hard ball", lol Lets see if we can get our heads together and get this resolved, please ** *Sincerely* *Steve* 1 of 1 3/22/2004 2 10 PM 211 site Subject: 211 site From: "Bonkers" <bonkers@mfire comma Date: Mon, 22 Mar 2004 11 57 50 -0500 To- "Linda Lewis" <Linda
