I am a 1099 misc contractor I am on a job 150 miles from my home. I rent an apartment that I occupy during the week. Is the rent deductable

Maybe. HOW LONG are you working in this job, using this apartment?

I have been at it 10 months

Yes, your daily living expenses for 2010 (rent, utilities, local transportation, incidental expenses, food) ARE deductible because the job is still considered to be temporary in nature.

However, if the job extends beyond February, 2011, then the job is no longer temporary and the expenses no longer deductible. Further, if you KNOWS the job will extend beyond February 2011, then the job was NEVER temporary in nature and the expenses are NOT deductible.
