Paranormal Contracts Oversight Commission (usually referenced by its acronym PCOC or P-COC, pronounced "peacock") is an overseeing committee created to supervise and warn the Ghostbusters if they are causing too much damage in their ghost capturing activities and can shut down the Ghostbusters' business if not taken seriously.
In 1991, the Ghostbusters were officially bonded contractors and expanded their business. During the Thanksgiving 1991 holiday, after the Ghostbusters' busts at the Sedgewick Hotel and Times Square, city council's concern for damages caused reached its limit. They ordered Mayor Jock Mulligan to place the Ghostbusters under close supervision for a period of no less than six months.  The Mayor accomplished this by appointing Walter Peck, the new head of PCOC.  PCOC was now assigned to keep them under control and keep the Office of the Mayor in the loop.  Peck was forced to deal with the Ghostbusters directly rather than shut them down and forfeit his new position.
PCOC sealed off the Sedgewick Hotel from the general public after the Ghostbusters' search for Slimer was completed. However, the posted notice made an effort to include the Ghostbusters among those excluded from entering the hotel. Egon Spengler dealt with the development by tearing PCOC's notice into shreds and the team entered the hotel once more.
Secondary Canon History
PCOC was reinstated after the "Infestation" event in order to keep the Ghostbusters in check for the good of the public and best interests of the city. A temporary office was set up in the Department of Public Safety at New York City Hall. PCOC's budget was slated to come up for review in the next quarter after summer. On March 1, 1994, a technical report was submitted and authored by Peck, D. Aykroyd, H. Ramis, and I. Reitman titled "Identification of Biometric Security Measures in relation to the Containment Unit (Storage Facility)." Part of the report outlined PCOC was unable to access the Containment Unit due to newly installed biometric security measures that only the senior staff had access to. It was concluded any attempt to override these measures could compromise the Containment Unit and lead to a catastrophic outcome.
In the fall, Peter visited Peck's office without an appointment to discuss the Ghost Smashers but left without an resolution. The Ghostbusters and Ghost Smashers were soon summoned to Peck's office to come up with a solution for the Megaspook.
The following year, PCOC forced members of Janine Melnitz's new team of Ghostbusters to sign a contract or face criminal charges. An addendum in the contract allowed the city to license and merchandise imagery connected to any new Ghostbuster approved by PCOC. There were several conditions as well that gave PCOC more scrutiny over the team. Janine's team were required to attend personal appearances and press events at PCOC's discretion and PCOC installed a liaison to coordinate and prioritize case loads. After the Ghostbusters returned, Peck called the liaison, Jack Hardemeyer, to his office and fired him. After the Tiamat incident, Jenny Moran was hired by Peck to more closely liaise between PCOC and the Ghostbusters.
Scandinavian entrepreneur Erland Vinter revealed he wanted to buy the Ghostbusters as part of a desire to clear prime real estate of paranormal activity then develop it. Walter Peck and Winston Zeddemore immediately recognized the idea as a fraudulent practice. Nonetheless, Peck insisted the sale was not in the best interest of New York City due to the specificity of the Ghostbusters' municipal contract. Walter Peck instead negotiated a loan of the Ghostbusters' services to Vinter. Under the contract, Vinter would have exclusive access to the Ghostbusters for up to two weeks in any given month for the standard rates plus a 15% commission payable to PCOC for any profits connected to ghost removal services provided.   Peck's compromise expanded PCOC's funding base, kept New York safe, and aced the Ghostbusters out of a buyout.
Janine and Jenny met with Peck in his office to discuss a request for reimbursement of nearly $400,000. Janine explained it was time-sensitive decision in relation to demands issued by Erland Vinter. Jenny reasoned the municipal agreements with the Ghostbusters established an emergency budget for use in prevention of foreseeable catastrophic paranormal events and okayed the charter jets to Chile and Japan. Janine and Jenny left, wishing him luck with the three sub-committees he would have to smooth things over with in regards to the budget. When the New York Police Department's officers are needed for security detail on investigations conducted by the Ghostbusters, they are paid triple time out of PCOC's budget.  A week after the latest Coney Island incident, Peck was visited by a representative from the EPA. He revealed the EPA was fining the Ghostbusters for willingly introducing a toxic element, a reservoir of mostly neutralized Psychomagnotheric Slime, to a residential area and also PCOC for not being able to keep them in check. The representative added if it were up to him, he would have their citizenship revoked and have them all deported to Guam. Peck mumbled angrily Guam was an American territory. On the day two Statues of Liberty appeared, PCOC announced a new budget report.
Kylie initiated Code Dan, an evacuation protocol worked out by the city and PCOC, and cleared the Grand Central Station when Connla was sighted. Peck had Janine over to his office for an 11:15 meeting. She didn't understand what was going on that couldn't be said over the phone. Peck steered the discussion to the death of Jenny and how she was now considered an unreliable resource. He and PCOC needed certainty, especially in the face of the Ghostbusters' ongoing exploration of the multiverse. Janine tried to downplay recent events but Peck recalled the dimensional bleed incident and Gozer. He surprised her with an offer to succeed Jenny as the new liaison. Peck requested an update from Janine but Kevin Tanaka came to the PCOC offices in her place. At around 5:10 pm, Peck asked how many Ghostbusters there were. Kevin estimated less than 50. Peck poured himself a drink and asked how many Peters there were. Kevin recalled two then Peck asked where they all were. Kevin replied they were at the Warehouse, where the Interspatial Teleportation Unit was moved. Peck still had questions about their interdimensional retrieval mission and the George Washington Bridge incident. He stopped himself and told Kevin to just take him through everything. Kevin started with Ron and Holtzmann's Remote Access Teleportation Unit glitching the Containment Unit and dispersing several ghosts into other dimensions. He stated how the main mission was to return all the ghosts into the unit then they could recalibrate and repair it. Kevin then went over the meeting at the Warehouse and what he learned of the George Washington Bridge incident from listening to Holtzmann's channel. Kevin ended with Holtzmann using a lighthouse fog horn and light to force the Doom Ghost to reveal itself. Peck couldn't believe he was serious. Kevin assured him he was definitely serious. Peck asked what happened to Janine. Kevin revealed Egon persuaded her to come along on the mission.
