tiny pool of stagnant water in the pipeline and eating away at the metal causing it to corrode. pg&e told state regulators last year that there was ongoing concern about the potential for internal corrosion along the 46-mile pipeline that ran from san francisco through san bruno down to milpitas. the corrosion has shown up in several tests along the line. an environmental microbe biologist outside of pg&e said any pipe as old as this one could have microbes hiding inside of it. the only way to check it is sending something in called a smart pig to check the walls or a cleaning pig which basically cleans out the gunk inside the pipeline. but the problem is the pipeline is too narrow and too many bends to allow either devise to run through the pipeline. another cause of the blast could be extension corrosion. the safety board is looking at all the possibilities. this investigation is expected to take up to a year.

meanwhile crews are still coming in here clearing out all this debris. it started yesterday. there are 37 homes of that been incinerated or basically totally destroyed so the cleanup continues today and actually we're going to have access around 10:00 this morning to see what's going on. the project is expected to take three to four weeks. after that this is basically going to be a dirt lot and neighbors can start to rebuild but some neighbors say it will never be the same. reporting live in san bruno, i'm jenelle wang, abc 7 news. >> thank you very much. it's 4:33 now. cleanup efforts will continue today in san bruno as crews move the remnants of 35 destroyed homes. the san mateo county will manage the $2 million job. officials expect it to take a month to clear the rubble and hope to have it all gone before the rainy season begins. this comes as san francisco's fire chief received a detailed map of the gas transmission lines under the city two weeks after she asked pg&e for it. abc 7's amy hollyfield explains.

>> here it is. the map of the gas lines running through san francisco. fire chief joanne hayes white asked for this a week ago. >> representatives of pg&e came to this building and hand-delivered a map to me as well as their pipeline integrity management system plan. >> a week ago pg&e refused to let her have it for security and safety reasons. we asked them about the change of heart. >> we looked at safety and security concerns, and realized there was a lot of interest from the public and a lot of concerns over the safety of our pipeline system and we wanted to do everything we could to allay that. >> now white thinks it's a tough decision. she understands why people want to know what's on this map. >> certainly as a mom of three boys and a property owner, you want to know where the lines run or how you're impacted. >> but she didn't let us see the map and tonight she told the fire commission pg&e had given her the information but didn't

discuss the details. >> i understand to give global information to everyone in a post-9/11 environment should be a concern. i have concerns personal. >> she did tell us the lines in san francisco do not run in densely populated areas. and the lines in the city hold half the pressure the san bruno lines have. >> i think we're going to be able to reassure the residents and give them as much information as we can without truly presenting safety risk, that kind of thing. that's my goal at least. >> amy hollyfield, abc 7 news. >> 4:35. a federal judge is expected to decide today if california can proceed with the execution of a convicted murderer next wednesday. the same judge ordered california to stop executions in 2006 and demanded changes in the lethal injection process. death penalty opponents claim the state hasn't met those requirements. the state says they have followed a judge's ruling by building a new death chamber and

has better trained staff. it wants to use the new facility at san quentin to execute albert brown on wednesday morning. >> the man accused of kidnapping jaycee dugard and holding her captive 18 years is expected back in court. phillip garrido's attorney may announce her client is mentally incompetent to stand trial. if the judge agrees to order a mental evaluation, it would put an immediate stop to the proceedings. both garrido and his wife nancy have pleaded not guilty. if he is found incompetent he will be sent to a state medical facility until he's competent to stand trial. >> california may be on the verge of breaking its budget stalemate. leaders agreed on a budget framework. they say they'll try to hammer out the details over the weekend and hope to announce a budget deal by monday and call lawmakers back to sacramento next week for hearings and a vote. >> what the framework actually means in real terms is that it's

been determined how much we will be spending in the coming year, how much we will be cutting in the coming year, what our levels of education funding will be and all the other details will be spelled out from there. >> republicans and democrats are split over whether to close the state's $19 billion deficit with tax increases or spending cuts. >> the state stalemate is putting another $932 million for transportation spending on hold, and that will affect the start of several projects in the bay area. our media partner the san jose mercury news reports the california transportation commission is delaying more than $32 million in contracts that would add merging lanes between university avenue and marsh road on highway 101 in san mateo county. also on hold more than $9 million for metering lights and chp pullout areas on 101 in san mateo county. and rebuilding the tully road interchange in san jose. >> the california field poll

to this overturned big rig. happened 3:00 this morning, the west 80 columbus parkway off-ramp is blocked. columbus parkway brings you that way towards the east. in addition to that the east 37 to columbus parkway is blocked until about 6:00 this morning. so you'll need to avoid that stretch as a detour and chp is recommending you head down westbound 80 to redwood street, turn around, and that way you can get back to columbus parkway. just seems like right underneath or right near that section of interstate 80 on the columbus park off-ramp, that's closed. isn't an easy detour in place but signs activated because they expect to be out there a couple hours at least. eric, kristen. >> frances, thank you very much. it's 4:40. >> the rough water that could sink san francisco's chances to host the most prestigious boat race in the world. >> no more nellie. the new leader the golden state warriors are expected to get on

here we have clear skies this morning and no breeze. without that breeze, we don't get the free air conditioning which means 6 to 12 degrees warmer today with 70s around the coast, 80s around the bay and 90s in our inland valley. the heat will peak on monday with hundreds in our east bay valleys, 90s the north bay and the south bay and up across parts of the peninsula and east bay shore with 80s all the way out to the coast. it's also monday when we could have poor air quality the east bay valley and santa clara valley. enjoy the fresher air this weekend. start with our temperatures today. remember, we're building up to that heat over the weekend. 80 dublin, low to mid-90s the rest of us, pleasanton 90 degrees. richmond the cool spot at 81, oakland 84 all the way to castro valley and fremont. mid to upper 80s south bay. possibly near 90 los gatos. on the peninsula today low to mid-80s with sunshine and on the

subject, change the focus from him and his stewardship of iran to issues that he's much more confident talking about. >> today president obama has an interviewed scheduled with bbc persia. it will be a chance for him to talk directly to the iranian people. emily schmidt, abc news, washington. >> a computer worm that experts think was designed to attack an iranian nuclear power station is causing international alarm. they believe it caused the facility to malfunction in june. the worm has since spread and infected about 45,000 industrial networks around the world. experts say the virus is so sophisticated it could only have been created with the backing of a government. experts say the worm can be transferred between machines by memory sticks. one says congress needs to give utility regulators authority to mandate protection. >> it's 4:56 now. coming up on abc 7 news at 5:00, a u.c. berkeley graduate freed from an iranian prison hopes to
