<div dir="ltr">Hello Tim,<div><br></div><div>This classification of Hall D engineering drawings is new to me, maybe it was presented at a meeting I missed. It raises new questions in my mind. If you don't know the answers, could you forward the message to someone who does?</div><div><ol><li>What specific content in these Hall D engineering drawings needs to be classified? Is it possible to black out certain titles, names or dates and declassify the drawings?</li><li>I think I have already violated the rule by posting floor maps of Hall B on my public web site at UConn (for more than a decade). If this is discovered, am I liable for violating Jlab security protocols?</li><li>Does Jlab have a security policy document telling what is allowed to be posted on a public web site and what is not?</li><li>Is this a policy that is enforced by DOE, or something the lab has voluntarily adopted?</li><li>Does this policy also cover drawings that were made by our group, and provided to the lab in fulfillment of a contract?</li></ol></div><div>-Richard J.</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Mar 23, 2016 at 3:08 PM, Timothy Whitlatch <span dir="ltr"><<a href="mailto:whitey@jlab.org" target="_blank">whitey@jlab.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
