Not sure what you're referring to.
It's in the petition for rulemaking. In addition to the local origination, there's also a proposal to extend §74.1201 to the 45 dBu contour on FM.
The people who promoted this petition has said nothing about the 45 dBu fill-in expansion, just like how the folks who supported C4 did not mention the proposed §73.215 changes in their "hype" about that proposal.
From their Petition:
FM COVERAGE CONTOUR CONFORMANCE FOR FM TRANSLATORS
10. The FCC in its recent FM Translator Interference Report and Order set a new standard for the coverage contour of all FM stations as the 45 dBμ contour in relation to FM translator stations. The recognition that FM radio stations have listeners out to, and their coverage contours extend out to, the 45 dBμ contour, should be now recognized in this proceeding to allow FM translators to better serve the listening public. In addition, the rule should be conformed to the AM rule with the 25-mile radius alternative. Sections 74.1201(g) – (j) of the FCC’s rules should be amended to specify the FM station coverage contour as used in Subpart L as follows:
(g) Translator coverage contour. For a fill-in FM translator rebroadcasting an FM radio broadcast station as its primary station, the FM translator's protected contour must be contained within the primary station's coverage contour. For purposes of this Subpart L, the coverage contour of all FM stations is the greater of either the predicted 45 dBμ contour or a 25-mile (40 km) radius centered at the FM transmitter site. The protected contour of an FM translator rebroadcasting an AM radio broadcast station as its primary station must be contained within the greater of either the 2 mV/m daytime contour of the AM station or a 25-mile (40 km) radius centered at the AM transmitter site. The protected contour for an FM translator station is its predicted 1 mV/m contour.
(h) Fill-in area. The area where the protected contour of an FM booster station is within the protected contour of the associated primary station (i.e., predicted 0.5 mV/m contour for commercial Class B stations, predicted 0.7 mV/m contour for commercial Class B1 stations, and predicted 1 mV/m contour for all other classes of stations), or the area where the protected contour of an FM translator station is within the coverage contour of the FM primary station.
(i) Other area. The area where the protected contour of an FM translator station extends beyond the coverage contour of the FM primary station.
(j) AM Fill-in area. The area within the greater of either the 2 mV/m daytime contour of the AM radio broadcast station being rebroadcast or a 25-mile (40 km) radius centered at the AM transmitter site.
As a consequence of this change in Sections 74.1201(g)-(j), certain conforming changes must also be made to 74.1232(d) and (e) as follows:
(d) An authorization for an FM translator whose protected contour as defined in §74.1201(g) extends beyond the coverage contour of the commercial primary station will not be granted to the licensee or permittee of a commercial FM radio broadcast station. Similarly, such authorization will not be granted to any person or entity having any interest whatsoever, or any connection with a primary FM station. Interested and connected parties extend to group owners, corporate parents, shareholders, officers, directors, employees, general and limited partners, family members and business associates. The coverage contour shall be as predicted in accordance with §73.313(a) through (d) of this chapter. In the case of an FM radio broadcast station authorized with facilities in excess of those specified by §73.211 of this chapter, a co-owned commercial FM translator will only be authorized within the coverage contour of the class of station being rebroadcast, as predicted on the basis of the maximum powers and heights set forth in that section for the applicable class of FM broadcast station concerned. An FM translator station in operation prior to March 1, 1991, which is owned by a commercial FM (primary) station and whose protected contour extends beyond the coverage contour of the primary station, may continue to be owned by such primary station until March 1, 1994. Thereafter, any such FM translator station must be owned by independent parties. An FM translator station in operation prior to June 1, 1991, which is owned by a commercial FM radio broadcast station and whose protected contour extends beyond the coverage contour of the primary station, may continue to be owned by a commercial FM radio broadcast station until June 1, 1994. Thereafter, any such FM translator station must be owned by independent parties. An FM translator providing service to an AM fill-in area will be authorized only to the permittee or licensee of the AM radio broadcast station being rebroadcast, or, in the case of an FM translator authorized to operate on an unreserved channel, to a party with a valid rebroadcast consent agreement with such a permittee or licensee to rebroadcast that station as the translator's primary station. In addition, any FM translator providing service to an AM fill-in area must have been authorized by a license or construction permit in effect as of May 1, 2009, or pursuant to an application that was pending as of May 1, 2009. A subsequent modification of any such FM translator will not affect its eligibility to rebroadcast an
AM signal.
(e) An FM translator station whose protected contour goes beyond the coverage contour of the commercial primary station shall not receive any support, before or after construction, either directly or indirectly, from the commercial primary FM radio broadcast station.
