ATTACHMENT 3: LETTER

July 11, 2001


Ms. XXXXXXXX
XXXXXXXXXXXXXXXXX
St. Paul, Minnesota 551XX

Dear Ms. XXXX:

This letter is written in response to your request for a report on the mercury contamination in your house.

We were informed that in early June service personnel under contract with Xcel Energy, removed a piece of equipment containing mercury from your natural gas line. It was reported that a small amount of mercury was spilled on your basement floor. Xcel hired BayWest to cleanup the mercury spill. Mercury vapor in the basement was measured with a Jerome Meter after the cleaning process was complete. The maximum Jerome reading after the cleanup was reported to be 349,000 ng/m3. This high concentration was not expected and therefore, questions about possible interference from ammonia in a cat litter box were raised. It was confirmed that kitty litter and other odorous material can interfere with correct readings on the Jerome meter.

Carol Hubbard, from the Minnesota Pollution Control Agency, and I accompanied Xcel Energy into the house on the afternoon of June 8th. Using a Lumex Mercury Vapor Analyzer, mercury levels were measured outside the house, on the main floor, and in the basement. Mercury concentrations in ambient air outside the house fluctuated between less than 30 ng/m3 and more than 150 ng/m3. The instrument readings appeared to stabilize below 30 ng/m3 when the instrument was held in the shade. Typical mercury concentrations outdoors are less than 10 ng/m3.

We entered the house through the back door into the kitchen and measured the mercury concentration to be between 1,500 and 3,500 ng/m3 in the kitchen. The mercury concentration increased on the stairs to the basement. Mercury concentrations in the basement ranged from 20,000 to 51,000 ng/m3. The Lumex is not thought to be sensitive to ammonia, and readings near the kitty litter box were consistent with what was encountered in other areas of the basement. According to the manufacturer, the sensitivity of the Lumex flattens out as mercury concentrations in air approach 50,000 ng/m3. Therefore, the actual mercury concentrations in air in the basement may have been higher in some areas.

Exposure to mercury concentrations above 6,000 ng/m3 for a long time (years) has been associated with hand tremors; increases in memory disturbances and other neurological effects. MDH advised Xcel that you, the owner of the house, be temporarily removed from the house until the house was re-cleaned to levels below the EPA Reference Concentration for mercury of 300 ng/m3. The RfC is considered protective for the general public, including sensitive sub-populations such as children, for life-time exposures. It is my understanding that you were relocated for the duration of most of the cleanup.

According to Xcel Energy, on Wednesday, June 13 contractors experienced in cleaning up mercury spills in basements (Weston, Chicago, IL) began cleanup operations. Cleaning methods included use of a mercury cleanup (amalgamating) kit, washing and scraping. Cleanup continued until all levels of mercury vapor, except those near the floor drain, were below the low-end calibration limit (1,000 ng/m3) on a Nippon mercury vapor survey meter. On Friday afternoon they sealed the floor with an enamel paint. Friday night the house was sealed up and heated to about 80º F.

On Saturday, June 16, I accompanied you and Xcel on what was to be a final inspection prior to clearance, or approval of reoccupancy. Mercury vapor concentrations on the main floor of your house were between 265 and 589 ng/m3. Mercury concentrations in the basement ranged from 881 ng/m3 to 1231 ng/m3.

Areas of the floor near the bottom of the basement stairs and a small partition on the north side of the eastern wall, as well as the washtub drain, were subsequently identified as areas which may be the source of some mercury vapor. The washtub and partition were removed. Some concrete was also excavated from the floor in areas where high mercury readings were recorded. Concrete patches were put in the floor and clear epoxy was used to seal these and other areas of the floor.

On June 20 Lumex sampling showed mercury vapor levels throughout the house to be below 300 ng/m3. On June 22, final clearance sampling was conducted by Franklin Dickson, Certified Industrial Hygenist, Applied Environmental Services, Inc. Following established protocols, the house was heated to between 75 and 80º F for two hours prior to drawing air samples over a 6 hour period. These sampling protocols were developed by the U.S. Environmental Protection Agency, and the Agency for Toxic Substances and Disease Control, a part of the U.S. Public Health Service.

Mercury concentrations throughout the house were below the identified level-of-concern of 300 ng/m3. Analytical results (Braun InterTech) are listed in the table below.
Sample # Location Mercury Concentration
1.
Living Room 210 ng/m3
2. Dining Room 180 ng/m3
3. Master Bedroom 140 ng/m3
4. Second Bedroom 100 ng/m3
5. Basement 270 ng/m3
6. Outdoors - back porch less than 100 ng/m3

MDH recommends that follow-up sampling be performed in the future to assure that these concentrations decrease over time, as expected.

MDH has concluded:

  • Xcel and Weston have certified that the cleanup was conducted using the best methods currently employed in mercury cleanups;
  • Applied Environmental Services and Braun Intertech certified that clearance data was acquired and analyzed according to protocols established by the EPA and ATSDR
  • The cleanup was successful in reducing potential exposures to mercury in air to levels below health concern.

In the next month, I will be writing a larger technical report on this incident. If I can be of further assistance, please let me know.


Sincerely,

ATTACHMENT 4: FINAL CLEARANCE SAMPLING PROTOCOL FOR MERCURY WITHIN A RESIDENTIAL HOME

This protocol is designed to be implemented once the on-site remediation service feels that the environment has been adequately cleaned and for the sole purpose of gathering valid data to be further assessed by                       and applicable governmental authorities.

Quantitative Sampling:

  1. Prior to sampling period, the indoor temperature of home environment should be determined and documented. Temperature should be at least 75-80º F for a minimum of 60 minutes prior to commencing sampling.

  2. Following the heating and venting period, the house should be closed up (windows, doors shut) for a minimum of 60 minutes after desired temperature of 75-80º F to allow for equilibrium temperatures to be achieved. Screen test area using screening protocol prior to final clearance. If there are readings above 0.0003 mg/m3 with continuous reading instruments, identify areas requiring recleaning, including additional ventilation. Record all readings on log sheet.

  3. The hopcalite test (sample attached)(SKC HYDRAR), or other approved method, will be used to provide final clearance if the detected mercury vapors were confined and there were no detectable levels in living areas prior to cleanup.

  4. If instrument testing is not used, final clearance sampling shall be performed utilizing USEPA Response Team SOP #1827 with a modified NIOSH 6009 method, 5/13/99 or OSHA ID-140. The pump will be calibrated to 0.5 liters/min. or less, or as defined by the method. The media utilized will be hopcalite or approved equivalent (e.g. Hydrar).

  5. One (1) field blank (opened in field and handled with samples) shall be taken for each home sampled. In addition, two (2) unopened blanks from the same lot shall be retained and submitted with the corresponding field blank.

  6. A minimum of five (5) samples should be taken throughout the home. All children's bedrooms and play areas shall be tested. In addition, one (1) outdoor reference sample shall be taken outside.

  7. A floor map of the home shall be drawn to document the locations selected for sampling. The floor map shall include occupancy information identifying the rooms sampled (i.e., children's bedrooms, play areas, etc.)

  8. The sample media shall be set at a height of between three to four (3-4) feet from ground level to represent a breathing zone sample.

  9. The sample time should be approximately eight (8) hours or as necessary to obtain a detection limit less than 0.0003 mg/m3. Periodic pump flow checks shall be performed and documented throughout the sampling period (minimum of 2).

  10. Upon completion of the sampling, samples shall be handled and submitted to an AIHA accredited laboratory for analysis utilizing proper chain of custody procedures. Sample turnaround time will be determined in advance by      .

  11. The analytical method to be utilized should be USEPA Response Team SOP #1827 with a modified NIOSH 6009 method, 5/13/99 or OSHA ID-140.

  12. Upon completion of the final clearance test and receipt of results, the sampling firm will prepare a clearance sampling report and submit to       for further review and follow-up action. The report shall consist of, at a minimum:

    1. Floor map documenting the locations of samples taken and corresponding results, including a description of the occupancy of the rooms tested.
    2. Sample data sheets documenting either the instrument readings or the media number, sample location, pump flow (with checks), final volume sampled, sample duration and any remarkable field notes.
    3. Sample results as submitted by the laboratory corresponding to provided sample data sheets, as applicable.
    4. Copy of this sampling protocol.

  13. The clearance sampling report will be submitted to USEPA, ATSDR and the IDPH for their review and determination of the effectiveness of the cleanup. A letter from IDPH to the residents will provide the final result of the consultation between USEPA, ATSDR and IDPH.
