I'll try to compose something coherent for the Wiki.

The primary frequency during the initial
response is CLEMAR, but is expected to shift at some point to CALCORD as
additional organizations join the MAC.

In central and northern California, OSPR wardens’ and biologists’ working
frequencies are 159.435Mhz(Tx) and 151.415Mhz (Rx). (CA Fish and Game)

CALCORD (VHF-FM 156.075Mhz) is the primary frequency for coordination among
state and local government agencies
in a multi-agency response.

Local fire and emergency medical services agencies also use frequencies within

Local law enforcement agencies, county sheriffs, and the California Highway Patrol
CLEMAR system for inter-jurisdictional coordination.

four primary VHF-FM frequencies and two primary UHF-FM
frequencies listed below for use in oil spill containment and cleanup operations.
1. 150.980Mhz VHF-FM*
2. 154.585Mhz VHF-FM
3. 158.445Mhz VHF-FM
4. 159.480Mhz VHF-FM
5. 454.000Mhz UHF*
6. 459.000Mhz UHF*

U.S. Coast Guard working frequencies:
Channel 81A (157.075Mhz) - Communication between U.S. Coast Guard units and
other Coast Guard personnel who are part of the OSC staff.
UHF 381.8 - The primary working frequency between the Unified Command and U.
Coast Guard aircraft.
Channe21A - Primary working/SAR frequency of Group Humboldt Bay.
Channe83A - Primary working/SAR frequency of Group Humboldt Bay.
Channel 16 - (156.8Mhz) Designated under international convention for use for
ship-to-ship and ship-to-shore hailing and distress in international waters. ALL users
are required to use channel 16 for only these purposes and then switch to other
channels for subsequent communications. Oil spill response is no exception.
Channel 13 - (156.65Mhz) Designated bridge-to-bridge hailing and navigation
safety frequency in inland and offshore waters. It may be used only to establish
contact and make arrangements between vessels in crossing, meeting, or overtaking
situations in accordance with the International or Inland Navigation Rules.
Ch. 06 (156.3Mhz) Safety Frequency -
is designated as the frequency which may
be used by all parties for communication on matters involving human health and
safety. FCC regulations require all vessels equipped with VHF-FM capability to have
this channel. As there is expected to be little other traffic on this channel during an
oil spill response, this should be monitored by all involved units that have this
channel available, and regarded as a tertiary channel for the response.
