Environment Agency Wales (EAW) is investigating a small oil leak at a tank storage facility in Pembrokeshire.
The incident happened on the SemLogistics site in Milford Haven.
Public Health Wales said health risks are likely to be low but air and water sampling is in place to monitor the situation.
EAW officers are assessing the impact of the leak but initial monitoring suggests the oil is contained.
