Mass. Gen. Laws ch. 6A, § 18H
(a) There shall be imposed on each subscriber or end user whose communication services are capable of accessing and utilizing an enhanced 911 system, a surcharge in the amount of 75 cents per month for expenses associated with services provided under sections 18A to 18J, inclusive, and sections 14A and 15E of chapter 166. For wireline enhanced 911 service, the charge shall be imposed on each voice grade exchange telephone line of business and residence customers within the commonwealth, but the surcharge applicable to centrex service and ISDN primary rate interface service shall be based on an equivalency ratio provided to each private branch exchange trunk. For wireless enhanced 911 service, the charge shall be imposed per wireless mobile telephone number, based on the area code chosen by the subscriber or end user. With the approval of the department, a wireless carrier may impose this surcharge based on the subscriber's or end user's billing address or other manner consistent with federal law. For interconnected VoIP provider service, the charge shall be imposed on each voice grade telephone line of business and residence customers within the commonwealth, but the surcharge applicable to such interconnected VoIP provider service that is comparable to centrex service and ISDN primary rate interface service associated with wireline enhanced 911 service shall be based on an equivalency ratio similar to that used for wireline enhanced 911 service. For IP–enabled service, the charge shall be imposed based on the subscriber's or end user's billing address in the commonwealth except for interconnected VoIP provider service, unless a different method is approved by the department. For prepaid wireless service, the department shall promulgate regulations establishing an equitable and reasonable method for the remittance and collection of the surcharge or surcharge amounts for such service. For all other services not identified above, the surcharge shall be imposed based on the subscriber's billing address in the commonwealth, unless a different method is approved by the department.
The surcharge shall be collected by the communication service provider and shall be shown on the subscriber's or end user's bill as ''Disability Access/Enhanced 911 Service Surcharge'', or an appropriate abbreviation. The surcharge shall not be subject to sales or use tax. The subscriber or end user shall be liable for the surcharge imposed under this section, and the communication service provider shall not be financially liable for surcharges billed on behalf of the commonwealth but not collected from subscribers or end users. Partial subscriber or end user payments shall be first applied to outstanding communication service provider charges.
(g) A communication service provider shall forward to any PSAP or any other answering point equipped for enhanced 911 service, or upon request consistent with federal law, to a municipal, state, or federal law enforcement agency, the department of telecommunications and cable, the FCC or the department, the telephone number and street address or location of any telephone used to place a 911 call, and any other call data or information required by the FCC to be transmitted to a PSAP.
Subscriber or end user information or data provided in accordance with this section shall be used, consistent with federal law, only for the purpose of responding to emergency calls, administering and operating the enhanced 911 system and providing enhanced 911 service, or for use in any ensuing investigation or prosecution, including the investigation of false or intentionally misleading reports of incidents requiring emergency service. No communication service provider or officers, directors, employees, vendors or agents shall be liable in any action to any person for releases of information authorized by this section or for civil action resulting from or caused by such providers for participation or omissions in the development, installation, operation, maintenance, performance or provision of enhanced 911 service except for wanton or willful misconduct. Release to or use by any person of a communication service provider's subscriber or end user information or data for any use other than the purposes enumerated in this subsection shall be prohibited. Notwithstanding any general or special law to the contrary, such information or data shall not be a public record under clause Twenty-sixth of section 7 of chapter 4 or section 10 of chapter 66, except that aggregated information that does not identify or effectively identify specific subscriber or end user information or data may be made public.
