Subject: Electronic copies for a project.
Attachments: SitePlan.pdf, Hydac BMP -SP -7 BMP DETAILS.pdf
Shelton is going to send you a stormwater permit application for a project called Hydac Technology or maybe Airlie
Industrial Park. The Project number is 11 -0089. Probably now called Phase 3. Anyway, I have attached electronic
copies of the two large plan drawings so you will not have to scan them in.

Plot Date: 5/28/14 File Name: K: \2013 \PN -19 Hydac Expan
