Back in July we reported on the adoption of new service rules to govern the H Block band. All but a small handful of those rules took effect in September, and one of the stragglers kicked in in November. According to a notice in the Federal Register, the Office of Management and Budget has now cleared the last of the rules, so with the publication of the Federal Register notice on January 17, 2014, they have become effective. According to the notice, OMB signed off on these rules on September 26, 2013; why it’s taken nearly four months for the Commission to publish a perfunctory notice reflecting that sign-off is a mystery. Whatever the reason, all of the new H Block rules are now in effect.
