MEMORANDUM

Mike Goodman appeals the district court’s grant of summary judgment to New Hampshire Insurance Company in his action for breach of contract, bad faith and violation of the consumer protection laws of the State of Washington. We affirm.

Goodman’s claims are all based upon state law; we, therefore, apply Washington law. ' See Erie R.R. Co. v. Tompkins, 304 U.S. 64, 78 , 58 S.Ct. 817, 822 , 82 L.Ed. 1188 (1938); Vestar Dev. II, LLC v. Gen. Dynamics Corp., 249 F.3d 958, 960 (9th Cir .2001).

(1) Goodman asserts that the district court erred when it ruled against his claim that the damage caused by a leak in a fuel tank was covered by the insurance policy issued by New Hampshire. We disagree. The policy covers damage caused by hidden defects, but excludes all coverage where damage or loss arises from corrosion. Giving the policy a “fair, reasonable, and sensible construction,” we agree with the district court that the policy unambiguously excluded coverage because the tank leak arose out of corrosion. To the extent that Goodman asserts that the efficient proximate cause of the problem was a leak from around the vessel’s hatches, there was no evidence that the hatch defect was hidden; again, coverage was unambiguously lacking.

(2) We also disagree with Goodman’s assertions that the district court erred when it granted judgment against him on his allegations that New Hampshire committed the tort of bad faith in handling and denying his claims, that it violated the Washington Consumer Protection Act, and that it violated the Washington Insurance Fair Conduct Act. The evidence he presented could not lead to a conclusion that he should have been granted additional benefits under the policy, or that the company breached its duties to communicate, disclose pertinent available benefits, investigate, issue a denial in a prompt manner, promptly explain its actions, and sufficiently maintain its files.

AFFIRMED.
