L. Homeland security and anti-terrorism measures


  • Alabama

    In 2004, the Public Records Law was amended to include the following language:

    [R]ecords concerning security plans, procedures, assessments, measures, or systems, and any other records relating to, or having an impact upon, the security or safety of persons, structures, facilities, or other infrastructures, including without limitation information concerning critical infrastructure (as defined at 42 U.S.C. §  5195c(e) as amended) and critical energy infrastructure information (as defined at 18 C.F.R. §  388.11(c)(1) as amended), the public disclosure of which could reasonably be expected to be detrimental to the public safety or welfare, and records the disclosure of which would otherwise be detrimental to the best interests of the public shall be exempted from this section. Any public officer who receives a request for records that may appear to relate to critical infrastructure or critical energy infrastructure information, shall notify the owner of such infrastructure in writing of the request and provide the owner an opportunity to comment on the request and on the threats to public safety or welfare that could reasonably be expected from public disclosure of the records.

    The Homeland Security and Emergency Management Subcommittee was established as a subcommittee of the Joint Armed Services Committee—which is a permanent interim committee of the legislature—to review confidential activities, plans, reports, recommendations and other materials of the Alaska division of homeland security and emergency management established in AS 26.20.025, or of other agencies or persons, relating to matters concerning homeland security and civil defense, emergencies or disasters in the state or to the state's preparedness for or ability to mount a prompt response to matters concerning homeland security and civil defense, emergencies or disasters. AS 24.20.680. Pursuant to section .680, the President of the Senate and the Speaker of the House of Representatives could condition service on the subcommittee by members upon the execution of appropriate confidentiality agreements by the members or by persons assisting those members. Information and documents received by members serving on the subcommittee or persons assisting members under a confidentiality agreement as described in this subsection were not public records and were not subject to public disclosure under the public records act. AS 24.20.680(d). AS 24.20.680 was repealed in 2009. Sec. 23-24, ch. 179 SLA 2004. The adjutant general of the Department of Military and Veterans Affairs was charged with proposing any appropriate legislation relating to this provision; it appears that sec. .680 has not been reinstated.
    Note also that a new category of records has been added to exempt from disclosure under the public records act records or information pertaining to a plan, program or procedures for establishing, maintaining or restoring security in the state, or to a detailed description or evaluation of systems, facilities or infrastructure in the state, but only to the extent that the production of the records or information (A) could reasonably be expected to interfere with the implementation or enforcement of the security plan, program or procedures; (B) would disclose confidential guidelines for investigations or enforcement and the disclosure could reasonably be expected to risk circumvention of the law; or (C) could reasonably be expected to endanger the life or physical safety of an individual or to present a real and substantial risk to the public health and welfare. AS 40.25.120(a)(10).

    Records of the expenditure of public moneys on security arrangements or investigations, including contracts for security arrangements and records related to the procurement of, budgeting for, or expenditures on security systems, shall be open for inspection, except to the extent that they contain specialized details of security arrangements or investigations. A custodian may deny the right of inspection of only the portions of a record that contain specialized details of security arrangements or investigations and shall allow inspection of the remaining portions of the record.
    A custodian may deny access to specialized details of either security arrangements or investigations or the physical and cyber assets of critical infrastructure, including the specific engineering, vulnerability, detailed design information, protective measures, emergency response plans, or system operational data of such assets that would be useful to a person in planning an attack on critical infrastructure but does not simply provide the general location of such infrastructure.

    In 2003, the General Assembly amended Indiana Code Section 5-14-3-4(b)(19) to include an additional discretionary exemption for information “which would have a reasonable likelihood of threatening public safety by exposing a vulnerability to terrorist attack.” See Ind. P.L. 173-2003 § 17. This section authorizes public agencies, at their discretion, to bar public disclosure of the following:

    (A) a record assembled, prepared or maintained to prevent, mitigate, or respond to an act of terrorism or an act of agricultural terrorism;

    (B) vulnerability assessments;

    (C) risk planning documents;

    (D) needs assessments;

    (E) threat assessments;

    (F) intelligence assessments;

    (G) domestic preparedness strategies;

    (H) the location of community drinking water wells and surface water intakes;

    (I) the emergency contact information of emergency responders and volunteers;

    (J) infrastructure records that disclose the configuration of critical systems such as communication, electrical, ventilation, water and wastewater systems;

    (K) detailed drawings or specifications of structural elements, floor plans, and operating, utility, or security systems of any building or facility located on an airport that is owned, occupied, leased, or maintained by a public agency;

    (L) the home address, home telephone number, and emergency contact information for certain emergency responders and public safety officers.

    Shortly after adopting the above exemption for materials whose disclosure would threaten public safety, the General Assembly added statutory guidelines that agencies must follow when using the Section 5-14-3-4(b)(19) exception to deny requests for records. The statute authorizes the agency to consult with the counterterrorism and security council, established under Indiana Code Section 10-19-8-1, prior to the denial. Ind. Code § 5-14-3-4.4(b). It further provides that, if the agency does deny the request under Section 5-14-3-4(b)(19), either the agency or the counterterrorism and security council must provide a general description of the record being withheld and of how disclosure of the record would have a reasonable likelihood of threatening the public safety.

    In 2002, the Legislature added what is now Iowa Code § 22.7(45), which provides:

    The critical asset protection plan or any part of the plan prepared pursuant to section 29C.8 and any information held by the homeland security and emergency management division that was supplied to the division by a public or private agency or organization and used in the development of the critical asset protection plan to include, but not be limited to, surveys, lists, maps, or photographs. However, the administrator shall make the list of assets available for examination by any person. A person wishing to examine the list of assets shall make a written request to the administrator on a form approved by the administrator. The list of assets may be viewed at the division's offices during normal working hours. The list of assets shall not be copied in any manner. Communications and asset information not required by law, rule, or procedure that are provided to the administrator by persons outside of government and for which the administrator has signed a nondisclosure agreement are exempt from public disclosures. The homeland security and emergency management division may provide all or part of the critical asset plan to federal, state, or local governmental agencies which have emergency planning or response functions if the administrator is satisfied that the need to know and intended use are reasonable. An agency receiving critical asset protection plan information from the division shall not redisseminate the information without prior approval of the administrator.

    (1) Security plans, security procedures or risk assessments prepared specifically for the purpose of preventing or preparing for acts of terrorism, but only to the extent that release of information contained in the record could reasonably be expected to jeopardize the physical safety of government personnel or the public; and

    (2) Records or information describing the architecture, design, access authentication, encryption or security of information technology infrastructure and systems.

    A 2002 amendment to G.L. c. 4, § 7, cl. 26 added subparagraph (n), which exempts:

    [R]ecords, including, but not limited to, blueprints, plans, policies, procedures and schematic drawings, which relate to internal layout and structural elements, security measures, emergency preparedness, threat or vulnerability assessments, or any other records relating to the security or safety of persons or buildings, structures, facilities, utilities, transportation or other infrastructure located within the commonwealth, the disclosure of which, in the reasonable judgment of the record custodian, subject to review by the supervisor of public records under subsection (b) of section 10 of chapter 66, is likely to jeopardize public safety.

    This exemption was enacted in response to the events of September 11, 2001 and was designed to increase security and prevent future attacks against persons and public places. It was intended to apply only to public buildings, public transportation, and public areas only. The exemption requires a custodian to balance the public right to know against public safety, and in doing so to take into consideration “all apparent facts and circumstances available.” The custodian must use "reasonable judgment" in granting or denying a request, and must “articulate with specificity” both the factors underlying that judgment and the basis for the belief that the records were “likely to be used” to endanger public safety. The custodian may not require a requester to provide additional information about him or herself or his or her motives, but the custodian may inform the requester that he or she will reevaluate a denied request if further information is voluntarily provided. Supervisor of Public Records (SPR) Bulletin, No. 04-03 (Apr. 1, 2003).The exemption was enacted even though the Legislature was advised that by requiring the custodian to make a “value judgment” about the requester, it is “specifically antithetic to the … presumptions that all records are public records and all requesters shall be treated uniformly.” Guide to the Massachusetts Public Records Law at 22–23 (Sec’y of State, rev. March 2009), Under this exemption, it is entirely possible, and permissible, that a custodian might properly provide requested blueprints to one requester, and deny the same blueprints to another.  Id.

    Records or information of measures designed to protect the security or safety of persons or property . . . whether public or private, including, but not limited to, building, public works, and public water supply designs to the extent that those designs relate to the ongoing security measures of a public body, capabilities and plans for responding to a violation of the Michigan anti-terrorism act . . . emergency response plans, risk planning documents, threat assessments, and domestic preparedness strategies.

    Mich. Comp. Laws Ann. § 15.243(1)(y).

    The Law has several provisions that implicate homeland security measures.

    Most importantly, the Law contains an exemption for any “record maintained by an agency in connection with the military, homeland security, national defense, law enforcement or other public safety activity that if disclosed would be reasonably likely to jeopardize or threaten public safety or preparedness or public protection activity or a record that is designated classified by an appropriate Federal or State military authority.” 65 Pa. Stat. Ann. § 67.708(b)(2). “Homeland security” is defined as any “[g]overnment actions designed to prevent, detect, respond to and recover from acts of terrorism, major disasters and other emergencies, whether natural or manmade.” 65 Pa. Stat. Ann. § 67.102.

    The Law also has an exemption applicable to records that, if disclosed, “create[ ] a reasonable likelihood of endangering the safety or physical security of a building, public utility, resource, infrastructure, facility or information storage system.” 65 Pa. Stat. Ann. § 67.708(b)(3); see Bowling v. Office of Open Records, 990 A.2d 813 (Pa. Commw. Ct. 2010) (requiring the Pennsylvania Emergency Management Agency to analyze each requested record to determine whether disclosure is “reasonably likely” to threaten the Commonwealth’s infrastructure).

    Section 552.101 of the Government Code exempts from disclosure "information considered to be confidential by law, either constitutional, statutory, or by judicial decision." Tex. Att'y Gen. Informal Letter Ruling No OR2011-05009 (2011). This section encompasses information protected by other statutes including the Texas Homeland Security Act. Id.

    The Texas Homeland Security Act added Sections 418.176 through 418.182 to chapter 418 of the Government Code. These provisions make certain information related to terrorism confidential. However, the fact that information may relate to a governmental body's security measures does not make the information per se confidential. Tex. Att'y Gen. OR 2011-05009 (2011); see Tex. Att'y Gen. ORD-649 (1996) (ruling that language of confidentiality provision controls scope of its protection). Furthermore, the mere recitation of the statute's key terms is not sufficient to demonstrate the applicability of the claimed provision. Id. As with any exception to disclosure, a claim must be accompanied by an adequate explanation of how the responsive records fall within the scope of the claimed provision. Id. (citing Tex. Gov’t Code § 552.301(e)(1)(A) (stating that a governmental body must explain how claimed exception to disclosure applies)).

    Under Section 418.181, documents or portions of documents in the possession of a governmental entity are confidential if they identify the technical details of particular vulnerabilities of critical infrastructure to an act of terrorism.

    Under Section 418.176, information is confidential if the information is collected, assembled, or maintained by or for a governmental entity for the purpose of preventing, detecting, responding to, or investigating an act of terrorism or related criminal activity and (1) relates to the staffing requirements of an emergency response provider; (2) relates to a tactical plan of the provider; or (3) consists of a list or compilation of pager or telephone numbers, including mobile and cellular telephone numbers, of the provider. Nurses licensed by the Texas Board of Nursing are not included within the meaning of "emergency response provider” and, therefore, the business facsimile numbers of nurses collected and maintained by the Board are not excepted from disclosure pursuant to Section 552.101 of the Act in conjunction with Section 418.176(a). Abbott v. Tex. Bd. of Nursing, No. 03-09-000154-CV, 2010 WL 392335, at *6 (Tex. App. ––Austin Feb. 3, 2010, no pet.) (mem. op.).

    Under Section 418.177, information is confidential if it (1) is collected, assembled, or maintained by or for a governmental entity for the purpose of preventing, detecting, or investigating an act of terrorism or related criminal activity; and (2) relates to an assessment by or for a governmental entity, or an assessment that is maintained by a governmental entity, of the risk or vulnerability of persons or property, including critical infrastructure, to an act of terrorism or related criminal activity.

    Under Section 418.178, information is confidential if it is information collected, assembled, or maintained by or for a governmental entity and (1) is more than likely to assist in the construction or assembly of an explosive weapon or a chemical, biological, radiological, or nuclear weapon of mass destruction; or (2) indicates the specific location of (A) a chemical, biological agent, toxin, or radioactive material that is more than likely to be used in the construction or assembly of such a weapon; or (B) unpublished information relating to a potential vaccine or to a device that detects biological agents or toxins.

    Under Section 418.179, information is confidential if the information (1) is collected, assembled, or maintained by or for a governmental entity for the purpose of preventing, detecting, or investigating an act of terrorism or related criminal activity; and (2) relates to the details of the encryption codes or security keys for a public communications system. Section 418.179 does not prohibit a governmental entity from making available, at cost, to bona fide local news media, for the purpose of monitoring emergency communications of public interest, the communications terminals used in the entity's trunked communications system that have encryption codes installed.

    Under Section 418.180, information, other than financial information, in the possession of a governmental entity is confidential if the information (1) is part of a report to an agency of the United States; (2) relates to an act of terrorism or related criminal activity; and (3) is specifically required to be kept confidential (A) under Section 552.101 because of a federal statute or regulation; (B) to participate in a state-federal information sharing agreement; or (C) to obtain federal funding.

    Under Section 418.182, information, including access codes and passwords, in the possession of a governmental entity that relates to the specifications, operating procedures, or location of a security system used to protect public or private property from an act of terrorism or related criminal activity is confidential. However, financial information in the possession of a governmental entity that relates to the expenditure of funds by a governmental entity for a security system is public information that is not exempt from required disclosure under Chapter 552.

    Additionally under Section 418.182, information in the possession of a governmental entity that relates to the location of a security camera in a private office at a state agency, including an institution of higher education, as defined by Section 61.003 of the Education Code is public information and is not exempt from required disclosure under Chapter 552 unless the security camera (1) is located in an individual personal residence for which the state provides security; or (2) is in use for surveillance in an active criminal investigation. See Tex. Dep’t. of Pub. Safety v. Abbott, 310 S.W.3d 670, 678 (Tex. App.–Austin 2010, no pet.) (DVDs containing video images recorded by the Texas Capitol’s security system were confidential and excepted from disclosure).

    Release of information relating to aviation security is governed by federal law. 49 U.S.C. §§ 114(a), (b)(1), 40119(b)(1); 49 C.F.R. §1520. The Attorney General has decided that requests for that kind of information should be directed to the Under Secretary of Transportation for Security who implements all regulations determining whether to disclose information sought pursuant to the federal Freedom of Information Act. See Op. Tex. Att'y Gen. No. OR 2004-3969 (2004). This includes personnel information of individuals working at airports or other facilities regulated by the United States Transportation Security Administration. Id.

    In its 2002 General Session, the Utah Legislature passed House Bill 283, which enacted and amended GRAMA’s provisions. The amendments responded to the terrorist attacks of September 11, 2001, on the World Trade Center in New York City and the Pentagon in Washington, D.C. amid growing concerns regarding the inability of existing law to deal with terrorist-type crimes. GRAMA now excludes from its coverage records of a government entity or political subdivision regarding security measures designed for the protection of persons or property, public or private, including security plans, security codes and combinations, passes and keys, security procedures, and building and public works designs, to the extent that the records relate to a public entity’s ongoing security measures. See Utah Code § 63G-2-106. In addition, information regarding food security, risk, and vulnerability assessments performed by the Department of Agriculture and Food is excluded from GRAMA’s scope. See id. § 63G-2-305(47).

    In 2003 the West Virginia Legislature amended FOIA by adding eight new exemptions related to homeland security and anti-terrorism planning. See, W. Va. Code § 29B-1-4(9) - (16). No judicial decisions have been reported which have involved any of the new exemptions.

    West Virginia Code section 29B-1-4 was further amended to add subsections (b) and (c), which provide that the term "terrorist act", as used in the new exemptions to the section, "means an act that is likely to result in serious bodily injury or damage to property or the environment and is intended to: (1) intimidate or coerce the civilian population; (2) influence the policy of a branch or level of government by intimidation or coercion; (3) affect the conduct of a branch or level of government by intimidation or coercion; or (4) Retaliate against a branch or level of government for a policy or conduct of the government. W. Va. Code § 29B-1-4 (b).

    West Virginia Code section 29B-1-4 (c) indicates that nothing in the eight anti-terrorism exemptions (subdivisions (9) through (16) ) of subsection (a) "should be construed to make subject to the provisions of this chapter any evidence of an immediate threat to public health or safety unrelated to a terrorist act or the threat thereof which comes to the attention of a public entity in the course of conducting a vulnerability assessment response or similar activity." W. Va. Code § 29B-1-4(c).  The precise meaning of this provision has not been the subject of judicial interpretation.

    Under the Aboveground Storage Tank Act, the public has “access to all documents and information submitted to the department pursuant to this article, subject to the limitations contained in the state Freedom of Information Act . . . or any information designated by the Division of Homeland Security and Emergency Management as restricted from public release.” W. Va. Code § 22-30-14(a).  “Trade secrets, proprietary business information and information designated by the Division of Homeland Security and Emergency Management as restricted from public release shall be secured and safeguarded by the department” and “shall not be disclosed to the public or to any firm, individual or agency other than officials or authorized employees or representatives of a state or federal agency implementing the provisions of this article or any other applicable law related to releases of fluid from aboveground storage tanks that impact the state's water resources.” Id. Disclosure of such information is subject to criminal penalties. Id.

    The Aboveground Storage Tank Act has other confidentiality provisions. For example, the “list of the potential sources of significant contamination contained within the zone of critical concern or zone of peripheral concern as provided by the Bureau for Public Health, working in conjunction with the department and the Division of Homeland Security and Emergency Management may only be disclosed to the extent consistent with the protection of trade secrets, confidential business information and information designated by the Division of Homeland Security and Emergency Management. . . .”  W. Va. Code § 22-30-14(b).  In addition, “[t]he exact location of the contaminants within the zone of critical concern or zone of peripheral concern is not subject to public disclosure in response to a Freedom of Information Act request. . . .” Id. “However, the location, characteristics and approximate quantities of potential sources of significant contamination within the zone of critical concern or zone of peripheral concern shall be made known to one or more designees of the public water utility, and shall be maintained in a confidential manner by the public water utility.” Id.
