components, such as maps, listed in a table at the end of the letter.

the 110(1)Reclamation Permit Application. If weather conditions prohibit an inspection of
the site prior to approval, then an inspection of the site will be scheduled as soon as
weather conditions allow.
Noted.

provide the dimensions of the portal to be used for the secondary escapeway and describe
