Its members are the governors of the four basin states—Delaware, New Jersey, New York, and Pennsylvania—and the North Atlantic Division Commander of the U.S. Army Corps of Engineers, representing the Federal government.

                    Notice of the proposed amendments appeared in the                     **Federal Register**                     (75 FR 41106) on July 15, 2010 as well as in the Delaware Register of Regulations (14 DE Reg. 70-83 (08/01/2010)) on August 1, 2010, the New Jersey Register (42 N.J.R. 1701(a)) on August 4, 2010, the New York State Register (p. 6) on July 21, 2010 and the Pennsylvania Bulletin (40 Pa. B. 4208) on July 31, 2010. A public hearing was held on September 23, 2010 and written comments were accepted through October 1, 2010. The commission received two written submissions and no oral testimony on the proposed changes. The Commission made minor revisions to the proposed amendments in response to the comments received.
