Public Comment on Nescopeck State Park Resource Management Plan
The
Greater Hazleton Area Astronomical Society was founded in 1977
to promote the study of astronomy and to provide an educational
function for the Greater Hazleton Area. Since the Society's inception,
we have been involved in science education through special astronomy
programs for public and private schools in the Hazleton area.
Our society also provides astronomy programs for local organizations,
scouting groups, the gifted-student program and the general public.
We operate an astronomical observing site in Eckley, PA where
we conduct astronomical studies and provide astronomy programs.
We
have reviewed the Resource Management Plan for Nescopeck State
Park. A summary of our comments is as follows and a discussion
of each comment is also provided below.
1.
The Resource Management Plan should recognize our night sky as
a fragile resource of the park. Steps should be taken to protect
it that include using only full cutoff shielded fixtures that
do not cause light pollution as required by local zoning ordinances.
2.
An area should be established in the park for astronomical studies
of the night sky.
3.
The planned Environmental Education Center should be designed
to allow astronomical observing programs for the public and for
astronomy presentations and light pollution educational programs
and studies.
Light
Pollution - Resource Management Plan
When
public input was sought on park plans years ago, our Society requested
that any lighting proposed for the park be full cutoff shielded
fixtures to avoid the light pollution problems of glare and skyglow.
We have attached recent articles on light pollution in our National
Parks where the problem has been extensively studied.
Since
1989, our Society has been working with local governments and
businesses in our area to reduce light pollution. The proposed
Nescopeck State Park would be located about six miles from our
astronomical observatory site in Eckley. Outdoor lighting ordinances
that require shielded lighting have been adopted in almost all
local municipalities. We have attached a copy of the Butler Township
ordinance that requires full cutoff fixtures. If any lighting
is proposed for the park, it should meet IESNA lighting level
standards and be full cutoff.
We
are requesting that the lighting type for any outdoor lighting
in the park be specified as Low Pressure Sodium (LPS). LPS is
the most energy efficient lighting type and its light can be filtered
for astronomical observing at the park using telescopes and binoculars
equipped with the appropriate filters. Our light pollution abatement
committee is available to assist the park with selection and design
of environmentally friendly lighting.
The
Pennsylvania 21st Century Environmental Commission was established
on July 11, 1997 by executive order from Governor Tom Ridge. In
the Governors Executive Order, the Governor asked the Commission
to recommend environmental priorities. The astronomical community
across the Commonwealth attended the Commissions meetings and
provided comments to the Commission to request that Light Pollution
be included as a top environmental issue for the State. The Governor
asked the Commission to propose strategies to meet environmental
priorities including proposed legislative and regulatory changes.
The astronomical community during the course of the public input
period recommended specific actions that could be taken to control
Pennsylvanias Light Pollution problem. These specific actions
included the following:
1.
Require that fully shielded lighting be used for all state funded
outdoor lighting so that no lighting is directed upward.
2.
Development of a Light Pollution Plan to protect areas of the
Commonwealth especially suitable for astronomical observatories
or which provide nocturnal benefits to flora and fauna.
The
Commissions Final Report to the Governor included a section on
Efficient Energy Use. This section included the following recommendation:
One
example of inefficiency is in the area of outdoor lighting that
is designed so that nearly half of the energy to light the lamp
is wasted upward instead of onto the ground. While it may appear
to be a relatively minor item, redesigning a bulb (fixture) is
the kind of solution or example that can be more broadly applied.
Our sound land use practices can include model ordinances for
outdoor lighting. Commonwealth procurement practices can be revised
to include a provision for efficient lighting. Such leadership
by example would produce efficient outlays of public funds, would
conserve energy and would reduce emissions.
The
parks Resource Management Plan should recognize our night sky
as a fragile resource of the park and our area. The night sky
has been lost to urban sky glow over most of Luzerne County and
this resource that still exists in the Nescopeck State Park needs
to be protected.
Area
for Astronomical Observation
Our
Society has been providing astronomy programs for the public at
Hickory Run, Tuscarora and Locust Lake State Parks. These programs
include astronomy and light pollution slide presentations, telescope
demonstrations and star parties for nighttime observing through
telescopes and binoculars. Our Society members volunteer their
time and equipment for the programs at no cost to the Commonwealth.
We
are requesting that the park be designed to set aside an area
for astronomical observing. Such an area could be as simple as
an open grassy field with an unobstructed view of the night sky.
We are available to assist with the selection of a site in the
park for this purpose.
Environmental
Education Center - Astronomical Observatory
We
recommend that the environmental education center be designed
to incorporate an astronomical observatory. An astronomical observatory
could become a primary attraction for such a center. The observatory
could be used during the day for solar observing and at night
for deep sky observing.
Through
our astronomy programs, our society has monitored air and light
pollution levels while building public awareness about clean air
and preservation of a fragile resource of our area, the night
sky. We have provided programs to the public on the effects of
light pollution on our night sky environment.
The
requirements for an astronomical observatory would vary. If incorporated
into the design of the environmental center, there may be no additional
cost to make accommodations for an observatory. Typical astronomical
observatories utilize a dome shaped roof that opens for telescope
viewing. Such a dome is typically 16 feet in diameter. Other observatory
designs instead use a slide-back roof to access the sky. A slide-back
roof allows for the use of multiple telescopes. Other alternatives
would be an observing deck as part of the environmental education
center building or a concrete or gravel pad adjacent to the building.
Our
society could provide three different types of telescopes that
are owned by the Society for nighttime observing. These are an
8 inch Celestron Schmidt-Cassegrain Telescope, a 6 inch Newtonian
Reflector Telescope and a 4 1/2 inch Refractor Telescope. The
8 inch Celestron Telescope is equipped with a clock drive mechanism
to track the movement of stars and can also be used for astrophotography
or connected to video equipment for observing by large groups.
Our
Society member leaders and volunteers would be available to assist
with the operation of the astronomical observatory as a community
service. Our society, as a non-profit educational organization,
has experience in providing educational programs since 1977. Regular
astronomy programs, environmental education programs and programs
for special astronomical events could be provided. The society
maintains an extensive astronomy library as well as audio visual
and exhibit materials. Solar observing programs, astronomy and
light pollution exhibits and astronomy slide presentations could
be available during the day.
Nescopeck
State Park offers a variety of locations for an observatory or
observing area. One criteria for selecting a site would be consideration
of the local terrain to maximize the portion of the sky that is
unobstructed. Our Society can assist in studying locations for
the site.
We
thank you for allowing our input on park plans. We are hopeful
that the night sky will be protected as an important fragile resource
of our area and that astronomy and light pollution education will
be made part of the parks educational objectives.
