Section P2902.5.3; change to read as follows:
P2902.5.3 Lawn irrigation systems. The potable water supply to lawn irrigation systems shall be
protected against backflow by an atmospheric -type vacuum breaker, a pressure -type vacuum breaker a
double -check assembly or a reduced pressure principle backflow preventer. A valve shall not be installed
downstream from an atmospheric vacuum breaker. Where chemicals are introduced into the system, the
potable water supply shall be protected against backflow by a reduced pressure principle backflow
preventer.
(Reason: To provide clarity.)

Exception: Cleanouts may be omitted on a horizontal drain less than 5 feet (1524 mm) in lenqth
unless such line is serving sinks or urinals.

Section P3112.2; delete and replace with the following:
P3112.2 Installation Traps for island sinks and similar equipment shall be roughed in above the floor
and may be vented by extending the vent as high as possible but not less than the drainboard height and
then returning it downward and connecting it to the horizontal sink drain immediately downstream from
the vertical fixture drain The return vent shall be connected to the horizontal drain through a wye- branch
fitting and shall in addition be provided with a foot vent taken off the vertical fixture vent by means of a
wve branch immediately below the floor and extending to the nearest partition and then through the roof
to the open air or may be connected to other vents at a point not less than six (6) inches (152 mm) above
the flood level rim of the fixtures served Drainage fittings shall be used on all parts of the vent below the
floor level and a minimum slope of one - quarter (1/4) inch per foot (20.9 mm /m) back to the drain shall be
maintained The return bend used under the drainboard shall be a one (1) piece fitting or an assembly of
a forty-five (45) degree (0.79 radius) a ninety (90) degree (1.6 radius) and a forty -five (45) degree (0.79
radius) elbow in the order named Pipe sizing shall be as elsewhere required in this Code. The island
sink drain upstream of the return vent shall serve no other fixtures. An accessible cleanout shall be
installed in the vertical portion of the foot vent.
(Reason: To clarify the installation of island venting and to provide a regional guideline on a standard
installation method for this region.)

ADDENDUM
to the 2012 and previous versions of the
Design Values for Wood ConsVuction
(a supplement to the Nadonal Design Specificadon• (NDSa) for Wood Construction)
Effective .tune 1, 2012, design values for No. 2 Dense and lower grades of visually- graded Southern Pine and No. 2 and
lower grades of visually - graded Mixed Southern Pine lumber, 2 "- 4" thick, 2 " -4" wide, will change. The design values
to use with the 2012 NOS, 2005 NDS, and the 2001 NDS are shown below (values that will change on June 1, 2012 are
shown as underlined):
Table 4B Reference Design Values for Visually Graded Southern Pine Dimension Lumber
(2" - 4" thick)1,2'2'4'5 (Tabulated design values are for normal bad duration and dry service conditions, unless
specified otherwise. See NDS 4.3 for a comprehensive description of design value adjustment factors.)

--Q. I auusasv ueahgn vanms are appscaae 10 lumber tnal will be used under dry conditions such as in most
covered structures. For 2" to 4" thick kmber the DRY dressed sizes shall be used (see Table 1A) regardless of the moisture content at
the lime of manufacture a use. In calculating design values, the nabiral gain in strength and stflness that occurs as lumber dries has
been taken Into consideration as wall as the reduction in sae that ocaas when unseasoned lumber shrinks. The gain in bad amytng
capacity due to increased strength and stf riess resulting from drying more than offsets the design effect of size reductions due to
STRESS -RATED BOARDS. Information for various grades of Southern Pine alress -rated boards of nominal 1 ", 1I %. and 1'r4" thickness,
2" and wider is available from the Southern Poe Inspection Bureau (SPIB) in the Sleridard Graft RuNs fix Southern Pine Lumber.
SPRUCE PINE. To obtain recommended design values for Spruce Pine graded to SPIS nies, multiply the appropriate design values for
Mbaid Southern Pine by the corresponding conversion factor shown below and round to the neemst 100,000 psi for E: to the nearest
10,1100 psi for E.*,: to the next lower multiple of 5 psi for F. and F«: to the next lower multiple of 50 psi for Fe, F,, and F. if 1,000 psi or
greater, 25 psi otherwise.
