10-144 C.M.R. ch. 222, § 5 - Information to be Contained in the Notice

A. Notice of a gaseous or liquid release shall include at least the following information:

1. Total amount of radioactivity released.

a. For scheduled releases the projection may be modified to account for errors in precision and shall include the total radioactivity to be released, combining batch and continuous releases. Gaseous and liquid releases must be reported separately.

b. For each unscheduled release, occurring as a separate event, the notice shall include the total amount of radioactivity released.

c. The total curies shall be reported in decimal equivalents (for example: 2.5 curies, 1.6 curies, 0.08 curies).

d. For each unscheduled release, the date and time of the release, as well as the duration.

2. The estimated individual dose that may occur as a result of the release.

Comparisons, if given to other sources of radiation exposure shall be consistent as to time of exposure. (As an example, comparisons to natural background radiation should be on the basis of average daily or hourly exposure to be consistent with the expected exposure time due to the release of radioactivity from the plant.)

3. A forecast of weather conditions at the time of the release.

A. The reported conditions should accurately reflect weather conditions most recently predicted for the vicinity of the plant at the time of the release.

B. For notices regarding unscheduled releases, data from the Maine Yankee meteorological tower and from direct observation of weather conditions should be used.

4. The area downwind from the release specified for the period of the release. The wind direction shall be given using the word "from." For example, the wind was from the Northeast at 8 miles per hour.

5. An explanation of the event, equipment malfunction, operator error, or other condition that caused the release.

6. Immediate corrective actions taken, for example, to remedy a malfunction or terminate the unscheduled release.

B. Breakdown of Safety Related Equipment

1. When a breakdown of safety related equipment occurs pursuant to Section 3.B.2, the notice shall include the equipment that malfunctioned and the error or other condition that led to the breakdown or malfunction in addition to the remedy to the situation.

2. If the aforementioned event results in a release, as defined in Section 2, a notice shall be given as indicated in Sections 3.A and 4.C. If no release occurs, any form of notice described in Section 4 may be utilized.
