      By Mr. CARDIN:
  S. 518. A bill to require States to establish highway stormwater 
management programs; to the Committee on Environment and Public Works.
  Mr. CARDIN. Mr. President, today I come to the floor to discuss the 
introduction of my latest legislative proposal to better control the 
harmful and volumes of polluted stormwater that is generated from our 
Nation's Federal aid highways. Highway stormwater is a growing threat 
to water quality, aquatic ecosystems and the fish and wildlife that 
depend on the health of these ecosystems. Moreover, the high volumes 
and rapid flow of stormwater runoff from highways and roads poses a 
very serious threat to the condition of our Nation's water and 
transportation infrastructure as well as personal property particularly 
in urban and suburban communities.
  The Environmental Protection Agency has recognized that pollution 
from point sources have been steadily declining since the enactment of 
the Clean Water Act. Likewise, we have seen reductions in pollution 
from certain non-point sources like agriculture which are attributable 
in part to the success of a wide variety of USDA Natural Resource 
Conservation Service Programs and farming innovations in soil 
conservation and nutrient pollution management.
  One non-point source sector where we are unfortunately seeing an 
increasing impact on water quality is from impervious surface that 
create rapidly moving high volumes of untreated polluted stormwater 
that rush off of road surfaces, erode unnatural channels next to and 
ultimately underneath roadways comprising the integrity of roadway 
infrastructure, and increases the stress on storm sewer systems 
shortening the useful life of this infrastructure and ultimately lead 
to the discharge of untreated pollution that is carried off roadways 
and into our lakes, rivers, streams, and coastal waters.

  Impervious surfaces include most buildings and structures, parking 
lots and of course the nearly 9 million lane miles of roads across our 
country. The total coverage of impervious surfaces in an area is 
usually expressed as a percentage of the total land area.
  The coverage increases with rising urbanization. In rural areas, 
impervious cover may only be 1 percent or 2 percent, however road 
surfaces comprise 80 percent-90 percent of a rural area's total 
impervious surfaces. In residential areas, impervious surface coverage 
ranges between 10 percent in low-density subdivisions to over 50 
percent in more densely developed communities, where the composition of 
the impervious surface area coverage works out to be 50 percent roads. 
In dense urban areas, the impervious surface area is often over 90 
percent the total land area, with roads comprising 60 percent-70 
percent of that coverage.
  According to EPA, urban impervious cover, not just roads, in the 
lower 48 adds up to 43,000 square miles--an area roughly the size of 
Ohio. Continuing development adds another quarter of a million acres 
each year. Typically two-thirds of the cover is pavement, roads and 
parking lots, and \1/3\ is buildings.
  According to the Chesapeake Bay Program, impervious surfaces compose 
roughly 17 percent of all urban and suburban lands in the Chesapeake 
Bay watershed. The greatest concentration of impervious surfaces in the 
bay watershed is in the Baltimore-Washington Metropolitan Areas of DC, 
Maryland and Virginia. The Virginia Tidewater area, Philadelphia's 
western suburbs, and Lancaster, PA, are also regions in the watershed 
where impervious surfaces are greater than 10 percent of the total land 
area.
  Rainfall on hard surfaces like roads and highways has a very 
destructive and turbulent affect on nearby waterways and 
infrastructure. For example, the rain events that occur over a week 
long period at the end of April brought nearly 8 inches of rain to the 
Baltimore-Washington region. The urban runoff from roads in Baltimore 
caused an embankment above the CSX railroad track along East 26th 
Street, between St. Paul and Charles Street, to collapse. Fortunately 
no one was injured though homes had to be evacuated for more than a 
month, nearly a dozen parked cars were destroyed and moreover movement 
of freight along CSX railroad was disrupted for more than a week. This 
event shows just how destructive and disruptive poorly managed 
stormwater from transportation infrastructure can be.
  Some may chalk this up to a freak storm of unusually large 
proportion. It's true this storm was unusual, but so were the polar 
vortexes and all of the snow New England and Buffalo received this 
winter, and 2013's 3-mile wide tornado in Alabama, the ongoing drought 
in California. ``Unusual'' weather seems to becoming a lot more usual. 
As extreme weather events triggered by our changing climate become more 
frequent it is imperative that we incorporate better designs into our 
infrastructure to be better handle these types of events.
  Under the Clean Water Act, stormwater is considered a non-point 
source and there are no requirements that stormwater be collected or 
treated. The exception being for localities where in order to meet the 
standards set in an MS4, Municipal Separate Storm Sewer System, permit 
a region may include its transportation infrastructure in its MS4 
permit.
  However, in most cases stormwater that falls on roadways washes oil, 
grease, asbestos brake-dust, nitrogen deposits from tailpipe emissions, 
trash, road salt and de-icing agents, and sediment into nearby 
waterways. Highway stormwater runoff is most often not treated or 
adequately managed.
  While these organic and inorganic contaminants are legitimate threats 
to water quality, the greater concern with roadway runoff is the sheer 
volume and rapid flow rate in which stormwater leaves these hard 
surfaces and enters our waterways. Flows and volumes that cause roads 
to collapse in Baltimore.
  Roads are designed for stormwater to flow off of the driving surface 
quickly, for safety reasons. When stormwater rushes off of road 
surfaces into storm drains it is usually piped straight into the 
nearest river or stream without removing contaminants, detaining any of 
the volume, or slowing down the flow. This creates an enormously 
destructive set of circumstances for our waterways.
  Another example of the destructive force that persistent unmitigated 
and poorly managed highway runoff can have on the condition and safety 
of highway infrastructure is in Mobile Alabama along Highway 131 in the 
Joe's Branch Watershed. The Mobile Bay Estuary Program, part of the 
National Estuaries Program, in coordination with Alabama Department of 
Transportation is having to spent millions of dollars to reinforce a 
highway embankment to keep the highway from slipping down a hill and 
into the Joe's Branch Creek, restore the hydrology of the river, and 
help protect private property from the dangerous erosion that's been 
caused by poorly managed stormwater from Highway 131.
  The Mobile Bay Estuary Program described the problem this way: ``In 
the Joe's Branch watershed, on the property of Westminster Village 
adjacent and parallel to Highway 131, a head cut stream is eroding at 
an accelerating rate, an ominous condition as ALDOT prepares to 
undertake improvements to the highway. Identified as a high priority 
stabilization area in the D'Olive Creek, Tiawasee Creek and Joe's 
Branch Watershed Management Plan, MBNEP has submitted a funding request 
to the Alabama Department of Environmental Management on behalf of its 
partners in Spanish Fort, Daphne, ALDOT and Westminster Village to 
undertake restoration of the stream using a cutting-edge technology 
called Regenerative Step Pool Storm Conveyance.''
  The four entities involved are spending large amount money to repair 
a problem caused by stormwater damage that could have been prevented at 
a lower cost by incorporating better stormwater mitigation facilities 
into the design of the highway.
  These high-volume/high-speed flows also hasten the deterioration of 
water infrastructure. A 2001 study on the erosive power of urban 
stormwater flows examined how excessive stormwater volumes and flow 
rates off of urban surface infrastructure caused more than $1 million 
in roadway and water infrastructure damage in the Cincinnati 
metropolitan areas in Ohio and Kentucky in a single year.
  While there are serious water quality concerns with not adequately 
controlling roadway infrastructure runoff, there are serious 
infrastructure costs, that are ultimately passed on to taxpayers and 
ratepayers, that can be avoided if transportation authorities do more 
to control and manage stormwater runoff with the infrastructure assets 
they manage and build.
  The increased incidence of flash flooding events that occur even 
during seemingly mild and routine storm events is a direct result of 
the growing percentage of impervious land cover in urban and suburban 
communities. Replacement of the ``greenscapes'' that are lost to 
pavement is essential to restoring hydrological balance to our urban 
and suburban communities and impaired watersheds.
  According to USGS: an inch of rain on one square foot of pavement 
produces 1.87 gallons of stormwater, Scaled up, 1 inch of rain on one 
acre would produce 27,150 gallons of stormwater. Using FHWA design 
standards for interstate highway lane and shoulder widths, 12 feet per 
lane, 10 foot right shoulder, 2x, 4 foot left shoulder, 2x, 10 miles of 
a four lane interstate highway generates nearly 2.5 million gallons of 
polluted stormwater for every inch of rain. To put that into 
perspective for the Potomac and Anacostia River Watersheds: The Capital 
Beltway, not including its 48 interchanges, generates nearly 30 
million, 29,920,946, gallons of polluted stormwater for every inch of 
rain that falls on the 64 mile 8 to 12 lane interstate highway loop. It 
is volumes of stormwater like that which cause dangerous streambank 
erosion.
  Gillies Creek is an urban waterway located East of Downtown Richmond. 
It is a tributary of the James River which flows into the Chesapeake 
Bay. Gillies Creek is surrounded by industrial and residential 
development and also receives stormwater from State highway 33, 
Interstate 64, US 60, and hundreds of city streets including Stony Run 
Parkway which directly adjacent to the creek for several miles.

The banks and bed of this creek have eroded so badly as urban 
development around the creek has added more impervious surfaces to the 
watershed that streambed sheering has created cliffs more than 10 feet 
tall at spots along the creek. Trees supporting the bank continually 
fall into the creek and nearby roadways and other infrastructure as 
well as homes and business are at risk. Reducing the impacts of the 
storms by mitigating the flow and volume of stormwater in this 
watershed will protect against further erosion and save the cost of 
repair and eventual replacement of the assets located along this 
endangered creek.
  The aim of this legislation is to improve highway designs to better 
manage stormwater to avoid the costly damage that poorly managed 
stormwater causes to infrastructure and nearby streams, rivers and 
coastal waters.
  I held a hearing on this issue in the Water and Wildlife Subcommittee 
on May 13, 2014. I heard many ideas from both the minority and majority 
witnesses that were invited to present testimony at this hearing. I 
listened to the concerns of my colleagues on the other side of the 
aisle and I have incorporated provisions into this bill that should 
alleviate concerns they may have had with previous attempts to better 
control highway stormwater.
  My bill's approach to highway runoff management is one that I hope my 
colleagues of both parties can support. First of all it put States in 
the driver's seat for developing hydrological analysis and 
implementation of best management practices to control highway runoff. 
The objective of the legislation is to control and manage flow and 
volume of stormwater from highways not to treat runoff in order to meet 
water quality standards. By taking this sort of approach we avoid EPA's 
involvement in the process. Lastly, States would only need to apply 
these procedures to new construction on major reconfiguration projects 
that significantly increases the amount of impervious surface in the 
project area.
  Title 23 of the U.S. Code states: ``transportation should play a 
significant role in promoting economic growth, improving the 
environment, and sustaining the quality of life'' through the use of 
``context sensitive solutions.'' In 2008, the Government Accountability 
Office issued a report examining key issues and challenges that needed 
to be addressed in the next reauthorization of the transportation bill. 
That report highlighted the clear link between transportation policy 
and the environment. With 985,139 miles of federal aid highways 
stretching from every corner of the US, polluted highway runoff is no 
small problem facing our Nation's waters. I would urge my colleagues to 
join me trying to address this problem facing America's waterways and 
infrastructure.
  Mr. President, I ask unanimous consent that the text of the bill be 
printed in the Record.
  There being no objection, the text of the bill was ordered to be 
printed in the Record, as follows:
