Railroad Transportation Center: Contaminated Soil Removal, Specification No. 99059 - Update The following is an update on the work to stockpile and remediate the soil coming from the Railroad Transportation Center. As part of the stockpiling permit application process the request for stockpiling the Railroad Transportation Center soil was forwarded to the Air Pollution Control District (APCD.) While they agreed in concept the material can be remediated to remove the Petroleum Hydrocarbons, they pointed out that the "lead" in the soil can not be remediated. Engineering staff discussed this with the staff at the Fire Department who confirmed this is correct. The lead in the soil is not of an amount that makes it regulated, "hazardous," and so neither the Fire Department nor the consultant raised it as an issue when remediation was discussed with Engineering. The lead is tightly bound to the soil and will not become soluble and leach out into waterways. However, the presence of the lead does mean the material will have limited uses and so will be more difficult to dispose of. In all probability, if stockpiled, it will have to be hauled to a disposal site at the end of the summer. APCD is asking several questions about whether the lead will become airborne or be of other risk to the public. While verbal comments from County Environmental Health and the City's consultant indicate that is not likely, the APCD will need some verification of this and the soil may have to be covered all the time. In order to satisfy the APCD, the City's consultant will have to model the material and determine how much dust can come off the material without being hazardous to people and then perform dust monitoring. Currently the piles are moist and not producing dust. It now appears the planned remediation effort is a losing battle. It will not produce a material that will be acceptable everywhere. It may take constant covering and monitoring to ensure there is no dust. Covering it, unfortunately, reduces the remediation process.. It now appears to be best to haul the material to a remediation disposal site as soon as possible and abandon the City's remediation effort. This is Alternative 2. in the Staff Report prepared for this item.

As part of the stockpiling permit application process our request was forwarded to the Air Pollution Control District(APCD.) While they agreed in concept the material can be remediated to remove the Petroleum Hydrocarbons, they pointed out that the "lead" in the soil can not be remediated. .I discussed this with our staff at the Fire Department who confirmed this is correct. The lead in the soil is not of an amount that makes it regulated - hazardous-and so neither our City staff or the consultant raised it as an issue when we discussed remediation. The lead is tightly bound to the soil and will not become soluble and leach out into water ways. However, the presence of the lead does mean the material will have limited uses and so will be more difficult to dispose of. In all probability it will have to be hauled to a disposal site at the end of the summer if we stockpile. APCD is asking several questions about whether the lead will become airborne or be of other risk to the public. While we have folks from County agencies and the City's consultant indicating that's not likely, the APCD will need some verification of this and we may have to keep it covered all the time. In order to satisfy the APCD our consultant will have to model the material and determine how much dust can come off the material without being hazardous to people and then perform dust monitoring. Currently the piles are moist and not producing dust. It now appears that the remediation effort we planned to undertake is a losing battle. It will not produce a material that will be acceptable everywhere. It may take constant covering and monitoring to ensure there is no dust. Covering it, unfortunately, reduces the remediation process. After discussing this with Engineering staff, we feel the best approach is to haul the material to a remediation disposal site once CC approves the funding and abandon the City's remediation effort.
