vehicles drive all over the playa most of the year, dripping leaking and spilling...
BRC occupies a small area (around 6.2 square miles, or ~3%) of the ~200 square miles of Black Rock Playa. BRC is located in one of the least biologically significant areas of the playa and with one of the lowest counts for the cyclic aquatic life of the playa. I'm guessing that BLM putting BRC on this location isn't an accident. Having BRC located there seems like a good precaution should, down the line, it turn up that something from accumulated BMs turns out to have had an effect, as due to the BRC location it will have had the least possible impact on playa life. This is more likely for BRC than random vehicles driving around the playa, as there is a greater likelihood of accumulating something with concentrated activity year after year, even though it's on the area of least possible significance. (we'll ignore the risk of random vehicles going where they will, and into more sensitive areas of the playa, and what a blown engine or mass leak from a gas tank may do at such a location - not relevant to what we
can do at BRC)
Addressing oil leaks is a proactive way of addressing something, while I believe not currently known to cause a problem, that down the line could turn out to have been an (accumulating?) issue that could have been addressed, minimized or contained.
I drive a 1986 AMC Eagle. It drips. That isn't going to change much.
I'm thinking a 4'x8' sheet of Masonite/hardboard ($14), fuzzy size up, and park all four wheels on it.
Addresses wheel/rubber "scars" and absorbs small drips at the same time. It can't blow away and I only need four nails to hold it while I drive on/off it?
